MEMORANDUM OPINION AND ORDER

Plaintiff Cheryl L. Hutchinson filed this suit on June 7, 2011, raising seven claims for relief. (Pl.’s Compl., Dkt. No. 1.) After the dismissal stage, Plaintiff has three claims remaining against both Defendant Dennis Phillips and Defendant City of Oklahoma City (“City”): (1) Count IV, which alleges a violation of equal protection, brought pursuant to 42 U.S.C. § 1983; (2) Count V, which alleges a violation of the Equal Pay Act; and (3) Count VI, which alleges negligent infliction of emotional distress. Three claims also survive against Defendant City alone: (1) Count II, which alleges gender discrimination and retaliation in violation of Title VII; (2) Count III, which alleges a hostile *1168work environment in violation of Title VII; and (3) Count VII, which alleges that Defendant City negligently supervised, trained, and retained its employees. Now before the Court is Defendant Dennis Phillips’s Motion for Summary Judgment (Dkt. No. 53) and Defendant City’s Motion for Summary Judgment (Dkt. No. 56). For reasons more fully set forth herein, the Court now GRANTS both Defendants’ Motions in FULL.

I. BACKGROUND

Plaintiff began working as a plant operator for the City of Oklahoma City at the Draper Lake Water Treatment Plant (“Draper Plant”) in 2004. As a plant operator, Plaintiff reported to a Chief Plant Operator (“CPO”), who in turn reported to the Water Operations Supervisor (“WOS”). Defendant Dennis Phillips has served as Water Operations Supervisor of the Draper Plant since September of 2006. Jim Crawford, the Plant Manager, is the direct supervisor of Dennis Phillips. For all periods of time relevant to this action, a collective bargaining agreement between the AFSCME union and the City of Oklahoma City governed the terms of Plaintiffs employment, including her pay. At all times relevant to this lawsuit, Plaintiff has received the highest rate of pay authorized for plant operators by the collective bargaining agreement. Plaintiff is the only female employee at the Draper Plant.

Plaintiff first told Jim Crawford that available overtime was not being distributed equally in March of 2008.1 On January 7, 2009, Plaintiff formally complained to the City’s “Ethics Hot Line” that Defendant Phillips had been improperly scheduling himself for overtime, falsifying the overtime equalization records, and going out to lunch once a week without clocking out and for longer than his allotted thirty-minute lunch break. Later that fall Plaintiff filed a grievance with the union,2 again alleging that Defendant Phillips had falsified the overtime equalization records. Plaintiffs grievance also accused Defendant Phillips of denying Plaintiff the opportunity to work as an “acting CPO,”3 denying her acting CPO pay for time worked in acting status, retaliating against her for filing her earlier complaint with the ethics committee, and creating a hostile work environment by making discriminatory and harassing statements. A hearing on Plaintiffs grievance was held February 24, 2010. As a result, management corrected the error in Plaintiffs pay and compensated her for the time she had worked as an acting CPO. However, the hearing officer found that “[t]here [was] no indication, other than the grievant’s personal opinion, that the grievant was not afforded *1169equal opportunities to work overtime. To the contrary, as one of the highest overtime earners, the grievant appears to have worked overtime more often than most of her male counterparts.” (Def.’s City’s Br., Dkt. No. 56, Ex. 12, at 2.) Plaintiff filed her first charge of discrimination with the EEOC two months later, on December 18, 2009, alleging discrimination on the basis of her gender and violations of the Equal Pay Act. Specifically, Plaintiff accused Defendant Phillips of falsifying the overtime equalization records, denying Plaintiff the same acting CPO opportunities as the other workers at the Draper Plant, who were all male, and encouraging her supervisor to harass her about her work and her use of company equipment and facilities. Plaintiff filed a second charge with the EEOC on April 12, 2011, repeating her earlier claims that Defendant Phillips encouraged her CPO to harass her, denied her overtime and “acting CPO” opportunities, and falsified the overtime equalization records. Plaintiff also alleged that Defendant Phillips paid males with equivalent or lesser qualifications more than her when they worked in equivalent “acting” positions. Plaintiff then filed her Complaint on June 7, 2011.

II. LEGAL STANDARD

Summary judgment is proper if the moving party “shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(a). A fact is material if it affects the disposition of the substantive claim. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). The party seeking summary judgment bears the initial burden of demonstrating the basis for its motion, and identifying those portions of “ ‘the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any,’ ” that demonstrate the absence of a genuine issue of material fact. Celotex Corp. v. Catrett, 477 U.S. 317, 323, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986) (citation omitted). If the movant satisfactorily demonstrates an absence of genuine issue of material fact with respect to a dispositive issue for which the non-moving party will bear the burden of proof at trial, the non-movant- must then “go beyond the pleadings and by her own affidavits, or by the ‘depositions, answers to interrogatories, and admissions on file,’ designate ‘specific facts showing that there is a genuine issue for trial.’ ” Id. at 324, 106 S.Ct. 2548. A. court considering a summary judgment motion must view the evidence and draw all reasonable inferences therefrom in the light most favorable to the nonmoving party. Kendrick v. Penske Transp. Servs., Inc., 220 F.3d 1220, 1225 (10th Cir. 2000).

III. ANALYSIS

A. Title VII

Counts II and III of Plaintiffs Complaint allege violations of Title VII of the Civil Rights Act of 1964 by Defendant City in the nature of gender discrimination, the creation of a hostile work environment, and retaliation. To prevent “ ‘the pressing of stale claims,’ ” aggrieved employees must file a charge of discrimination with the EEOC within 300 days of the allegedly unlawful act. Montes v. Vail Clinic, Inc., 497 F.3d 1160, 1163 (10th Cir. 2007) (quoting Zipes v. Trans World Airlines, Inc., 455 U.S. 385, 394, 102 S.Ct. 1127, 71 L.Ed.2d 234 (1982)); see also 42 U.S.C. § 2000e-5(e)(1). For discrete acts of discrimination, the 300-day time period begins running when an employee first learns of the disputed employment action. Almond v. Unified Sch. Dist. No. 501, 665 F.3d 1174, 1177-78 (10th Cir. 2011). Thus, the Court will only look at individual incidents of discrimination occurring on or after February 22, 2009 — 300 days before *1170Plaintiff filed her first EEOC charge.4 Courts apply a special “ongoing violation” rule to hostile work environment claims because such “claims are different in kind from discrete acts,” in that “[t]heir very nature involves repeated conduct.” Nat’l R.R. Passenger Corp. v. Morgan, 536 U.S. 101, 115, 122 S.Ct. 2061, 153 L.Ed.2d 106 (2002). In Morgan, the Supreme Court held that all “the incidents constituting a hostile work environment are part of one unlawful employment practice;” thus, Plaintiffs claim is timely so long as at least one act contributing to the hostile work environment took place within Title VII’s 300-day period. Id. at 118, 122 S.Ct. 2061. The Court will consider both actions within and outside the 300-day period so long as “ ‘the pre-and post-limitations period incidents involve[d] the same type of employment actions, occurred relatively frequently, and were perpetrated by the same managers.’ ” Id. at 120, 122 S.Ct. 2061 (citation omitted).

1. Gender Discrimination: Discrete Acts

The McDonnell Douglas5 burden-shifting framework applies when a plaintiff asserts a gender discrimination claim but cannot produce any direct evidence of discrimination. Daniels v. United Parcel Serv., Inc., 701 F.3d 620, 627 (10th Cir. 2012). Under McDonnell Douglas, Plaintiff has the initial burden of establishing a prima facie case of gender-based discrimination. Id. Plaintiff must demonstrate “(1) membership in a protected class and (2) an adverse employment action (3) that took place under circumstances giving rise to an inference of discrimination.” Id. If Plaintiff meets her burden, Defendant City must then articulate “a legitimate nondiscriminatory reason for its actions.” Id. If the City does so, Plaintiff must “introduce evidence that the stated nondiscriminatory reason is merely a pretext for discriminatory intent.” Id. Defendant City concedes that Plaintiff is a member of a protected class and therefore challenges only the second and third elements of Plaintiffs prima facie case.

Defendant City first argues that Plaintiff cannot establish her prima facie case because she has not suffered an adverse employment action, or something affecting her “compensation, terms, conditions, or privileges of employment.” See 42 U.S.C. § 2000e2(a)(1). It is true that Plaintiff has not been terminated, demoted, disciplined, or had her salary reduced. Nor did Defendant Phillips ever rate her less than “fully competent” in her annual performance evaluations. Nevertheless, Plaintiff alleges four incidents6 of discrimi*1171nation since February 22, 2009, that interfered with her compensation, all of which she claims took place under circumstances giving rise to discrimination.

First, Plaintiff contends that in 2010 Defendant Phillips refused to allow Plaintiff to receive emergency call-out time even though she had heard that a male employee, Art Ford, had received call-out time the previous year. (Pl.’s Resp. to Def. City, Ex. 3 at 410-411, 450.) When Plaintiff asked Defendant Phillips why she could not receive call-out time, he allegedly responded, “I don’t know why you don’t get it.” (Id., Ex. 3 at 410.) Plaintiff did not ask any of her other supervisors why she could not have call-out time, nor did she file a complaint or grievance, despite having previously utilized the available grievance procedures. (Id., Ex. 3 at 411.) Other than her belief that one employee had received emergency call-out time in a prior year, Plaintiff admits she has no information about who else did or did not receive call-out pay. (Id., Ex. 3 at 450.) A memo issued the following year clarifies that City policy is to not pay “emergency overtime” or “call back” time. (Def. City’s Br., Ex. 5 at 5.) Under these facts, Plaintiff has not raised an inference that Defendant Phillips’s denial of emergency call-out time related to her gender.

Plaintiff also alleges that Defendant Phillips filed a false report after Plaintiff suffered an on-the-job injury in March 2010. Although Plaintiff does not describe her injury, Defendant Phillips explains that Plaintiff submitted a claim after sticking her finger with a staple from a magazine she was reading. (Reply of Def. Phillips, Dkt. No. 67, at 6.) In his report, Defendant Phillips stated that Plaintiff was on her lunch break when she sustained her injury, which caused the Workets’ Compensation Court to initially deny her claim. After Plaintiff appealed that decision, arguing that she does not have an unpaid lunch break since she is required to be on the clock during her entire shift, the Workers’ Compensation Court found in her favor and the City compensated Plaintiff for her injury. Plaintiff does not allege facts indicating that Defendant Phillips stated she was on her break maliciously or with the intent of causing the Workers’ Compensation Court to deny her claim. Rather than being related to Plaintiffs gender, Defendant Phillips’s report that Plaintiff injured herself while on a break mostly likely stems from the fact that she was reading a magazine when the injury occurred.

Next, Plaintiff claims that Defendant Phillips falsified Plaintiffs overtime balance in the overtime equalization records in order to deny her overtime opportunities. Plaintiffs evidence for this con*1172tention mostly consists of her own beliefs7 and that in 2009 she complained to Jim Crawford, the Plant Manager, about several entries in the equalization records and asked for certain credits to be removed.8 (Pl.’s Resp. to Def. City, Ex. 3 at 298-99, 397-98, 426.) Specifically, Plaintiff argued that she should not have been credited overtime on September 13, 2009, when Defendant Phillips attempted to offer her overtime but someone else accepted the opportunity before Plaintiff called back. (Id., Ex. 3 at 298.) Yet City policy allowed Defendant Phillips to call the next person on the overtime list if Plaintiff had not responded within fifteen (15) minutes. Plaintiff also relies on an instance in April of 2009 where she contested the addition of four (4) hours to her overtime balance, which Art Ford claimed “at least looked suspicious.” (Id., Ex. 1 at 165-66, Ex. 3 at 298.) However, Plaintiffs claims that Defendant Phillips falsified the overtime equalization records in 2009 were investigated after Plaintiff filed an AFSCME grievance. The corresponding report, issued after a hearing in early 2010, found that “[t]here is no indication, other than the grievant’s personal opinion, that the grievant was not afforded equal opportunities to work overtime.” (Def. City’s Br., Ex. 12 at 2.) Moreover, according to Defendant City, Plaintiff worked the second most overtime hours for calendar year 2009,9 more than all but one of her male co-workers, belying her assertions that Defendant Phillips denied her overtime on the basis of her gender.10 (Id., Ex. 19.)

Finally, Plaintiff argues that Defendant Phillips attempted to block her from serving as acting CPO on account of her gender, as evidenced by the fact that he allowed males with less experience and qualifications to serve more time as acting CPO than Plaintiff. Other than her own assertions, Plaintiff relies on two pieces of evidence: first, testimony that Defendant Phillips was upset that she served as acting CPO in October of 2009 and, second, that a male co-worker with less experience and lower licenses worked more acting CPO hours than she did. (Pl.’s Resp. to Def. City, Ex. 1 at 157-159, Ex. 3 at 290, 395-96.)

*1173In his deposition, Art Ford, a co-worker, testified that one time Defendant Phillips seemed “upset” after finding out that Plaintiff had served as acting CPO during his vacation. (Id., Ex. 1 at 158.) However, even if Defendant Phillips was “upset,” this does not provide evidence of gender bias. Before leaving for vacation, Defendant Phillips prepared a schedule designating Ford acting CPO for Ford’s regular shift in accordance with the Draper Plant’s new acting CPO scheduling policy. (Def. Phillips’s Br., Dkt. No. 54, at 15.) Without Defendant Phillips’s knowledge, Jim Crawford changed the schedule. (Id.) Given the evidence that Defendant Phillips had a “rigid requirement” that the rules be followed, the fact that Defendant Phillips may have been upset when he discovered the schedule change does not indicate gender discrimination. (Id. at 21, Ex. 17 at 34, Ex. 18 at 78, 81.)

Plaintiff also argues that the number of hours worked by Ryan Osborn, a male eoworker with less experience and lower licenses, indicates an effort to prevent her from serving as acting CPO because of her gender. Plaintiff is correct that Ryan Osborn11 worked more hours as acting CPO than she did in 2009 and 2010 and that in 2009 Ryan Osborn had only a class C license while Plaintiff had class A and B licenses. (Def. City’s Br., Ex. 19; Pl.’s Resp. to Def. City, Ex. 3 at 318-19.) However, in scheduling Ryan Osborn to work as acting CPO, Defendant Phillips followed a neutral City policy that required the plant operator already scheduled for the shift to work as acting CPO. Plaintiff complained that this policy hurt her financially because she qualified for less acting CPO hours than she did before the policy’s implementation, but she conceded that the policy was fair because it applied to everyone equitably. (Def. Phillips’s Br., Ex. 16 at 330-31.) Defendant City also disputes Plaintiffs contention that Defendant Phillips prevented her from working in. an acting CPO capacity because of her gender by noting that despite being the only woman at the Draper Plant, she worked the second highest total number of acting CPO hours for calendar years 2009 through 2011. (Def. City’s Br., Ex. 7 at 1-2, Ex. 19.) Moreover, the evidence indicates that on at least one occasion, Plaintiff actually turned down the opportunity to work as acting CPO. (Pl.’s Resp. to Def. City, Ex. 3 at 290, 388.)

Because the discrete acts alleged by Plaintiff to constitute gender discrimination in violation of Title VII do not amount to adverse actions and she offers insufficient evidence to support her beliefs that the actions were taken on account of her gender, Plaintiffs claim fails and summary judgment is appropriate for Defendant City.

2. Gender Discrimination: Hostile Workplace

In Meritor Savings Bank, FSB v. Vinson, 477 U.S. 57, 66, 106 S.Ct. 2399, 91 L.Ed.2d 49 (1986), the Supreme Court held that “a plaintiff may establish a violation of Title VII by proving that discrimination based on sex has created a hostile or abusive work environment.” An employer can be held liable for an individual employee’s harassment “on a negligence theory, ‘if it knew or should have known about the conduct and failed to stop it.’ ” Bertsch v. Overstock.com, 684 F.3d 1023, 1027 (10th Cir. 2012) (quoting Burlington Indus., Inc. v. Ellerth, 524 U.S. 742, 759, 118 S.Ct. 2257, 141 L.Ed.2d 633 (1998)). Taking “remedial and preventative action ‘reasonably calculated to end the harass*1174ment’ ” will absolve an employer of liability for acts of harassment by its employees. Duncan v. Manager, Dep’t of Safety, City & Cnty. of Denver, 397 F.3d 1300, 1310 (10th Cir. 2005) (quoting Adler v. Wal-Mart Stores, Inc., 144 F.3d 664, 676 (10th Cir. 1998)).

Not all harassment creates an actionable hostile work environment claim under Title VII. To bring a claim of gender discrimination based on a hostile work environment, Plaintiff must establish (1) discrimination on the basis of her gender and (2) that the discrimination was “sufficiently severe or pervasive to alter the conditions of the victim’s employment and create an abusive working environment.” Penn. State Police v. Suders, 542 U.S. 129, 146-147, 124 S.Ct. 2342, 159 L.Ed.2d 204 (2004) (quoting Meritor Sav. Bank, 477 U.S. at 67, 106 S.Ct. 2399); see also Morris v. City of Colo. Springs, 666 F.3d 654, 663 (10th Cir. 2012). Gender discrimination by way of a hostile work environment must be sufficiently severe or12 pervasive because “Title VII does not establish ‘a general civility code’ for the workplace.” Morris, 666 F.3d at 663-64 (quoting Oncale v. Sundowner Offshore Servs., Inc., 523 U.S. 75, 81, 118 S.Ct. 998, 140 L.Ed.2d 201 (1998)). Thus, “the run-of-the-mill boorish, juvenile, or annoying behavior that is not uncommon in American workplaces is not the stuff of a Title VII hostile work environment claim.” Id. at 664.13 Moreover, to prevail on a hostile work environment action, Plaintiff “ ‘must show that the environment was both objectively and subjectively hostile or abusive.’ ” Id. at 664 (quoting Davis v. U.S. Postal Serv., 142 F.3d 1334, 1341 (10th Cir. 1998)) (emphasis added). Accordingly, the Court looks to the “totality of the Circumstances” to determine “the objective severity of the harassment from the perspective of a reasonable person in the plaintiffs position,” including “such factors as the frequency of the discriminatory conduct; its severity; whether it is physically threatening or humiliating, or a mere offensive utterance; and whether it unreasonably interferes with an employee’s work performance.” Id. (internal quotation marks and citations omitted).

Plaintiff identifies three incidents to support her claim of a hostile work environ*1175ment that are overtly gender-related. First, Plaintiff alleges that in February of 2009, Defendant Phillips referred to her as a “cunt” when talking to Art Ford. Art Ford testified that Defendant Phillips said, “[t]he cunt had done it to me again,” in reference to Plaintiff reporting him for using his city vehicle to take his wife to lunch. (Def. Phillips’s Br., Ex. 14 at 44-46, 49-50; Pl.’s Resp. to Def. City, Ex. 1 at 154-55.) Next, Plaintiff points to testimony alleging that Defendant Phillips did not want Diane, a female operator at another plant, to come to the Draper Plant because the Draper Plant already had “one and the other plant should have one too.” (Pl.’s Resp. to Def. City, Ex. 2 at 157.) Art Ford testified that he interpreted this comment to mean that Defendant Phillips did not like to work with women. (Id., Ex. 1 at 162-63.) Finally, Plaintiff testified that Defendant Phillips referred to another woman as a “stupid bitch” in her presence. (Id., Ex. 2 at 157.)

Isolated incidents of offensive comments will not support a finding of a pervasively hostile work environment. Morris, 666 F.3d at 666 (“A plaintiff does not make a sufficient showing of a pervasively hostile work environment ‘by demonstrating a few isolated incidents of ... sporadic ... slurs.... Instead, there must be a steady barrage of opprobrious ... comments.’ ” (quoting Chavez, 397 F.3d at 832)). Neither are such statements, alone, sufficiently “severe.” Id. at 666-67 (noting the distinguishable nature of earlier cases finding isolated incidents severe enough to support a hostile work environment; such incidents involved instances of sexual assault and “especially egregious or extreme” conduct). However, Plaintiff claims that these statements must be viewed in the context of Defendant Phillips’s other discriminatory actions.

In Chavez, the Tenth Circuit recognized that “ ‘[f]acially neutral abusive conduct can support a finding of gender animus sufficient to sustain a hostile work environment claim when that conduct is viewed in the context of other, overtly gender-discriminatory conduct.’ ” 397 F.3d at 833 (quoting O’Shea v. Yellow Tech. Servs., Inc., 185 F.3d 1093, 1097 (10th Cir. 1999)). As additional support for her hostile work environment claim, Plaintiff alleges Defendant Phillips disproportionately and disparately criticized her over minor work-related matters, such as her use of Draper Plant facilities, her cell phone usage, and not carrying her radio. Plaintiff also argues that Defendant Phillips was more “harsh” with her when she made work-related mistakes, such as allowing her clearwell level to get too low and accidentally entering information incorrectly in a logbook, and that he encouraged her direct supervisors, the CPOs, to harass her. Plaintiff offers little evidence in support of her allegations other than her own testimony and fails to address the conflicting testimony of other employees at the Draper Plant.14 However, even disregard*1176ing evidence contrary to Plaintiffs accusations, Plaintiff has not made out a claim of a hostile work environment, as she has not shown that Defendant Phillips discriminated against her because of her gender by creating a work environment so hostile and abusive as to alter the terms, conditions, and privileges of her employment. Under the totality of the circumstances, summary judgment is appropriate for Defendant City.

3. Retaliation

Plaintiff has also asserted a Title VII retaliation claim against Defendant City. Title VII’s anti-retaliation provision makes it unlawful for an employer to discriminate against an employee who has opposed harassment or discrimination in the workplace. 42 U.S.C. § 2000e-3(a). To establish a prima facie case of retaliation under McDonnell Douglas, Plaintiff must show: “(1) ‘she engaged in protected opposition to discrimination, (2) a reasonable employee would have considered the challenged employment action materially adverse, and (3) a causal connection existed between the protected activity and the materially adverse action.’ ” Daniels, 701 F.3d at 638 (quoting Hinds v. Sprint/United Mgmt. Co., 523 F.3d 1187, 1202 (10th Cir. 2008)). Defendant City concedes that Plaintiff engaged in protected opposition to discrimination when she filed a charge with the EEOC on December 18, 2009,15 but denies that Plaintiff suffered a materially adverse action causally related to her discrimination charge.

*1177Title VIPs anti-retaliation provision “protects an individual not from all retaliation, but from retaliation that produces an injury or harm,” or actions that “a reasonable employee would have found ... materially adverse.” Burlington N. & Santa Fe Ry. Co. v. White, 548 U.S. 53, 67-68, 126 S.Ct. 2405, 165 L.Ed.2d 345 (2006). A materially adverse action is one that “might have dissuaded a reasonable worker from making or supporting a charge of discrimination.” Id. at 68, 126 S.Ct. 2405 (internal quotation marks and citations omitted). To be actionable, Plaintiff must have suffered an “injury rising to a ‘level of seriousness.’” Daniels, 701 F.3d at 638 (quoting Williams v. W.D. Sports, N.M., Inc., 497 F.3d 1079, 1087 (10th Cir. 2007)). The materiality requirement “separated] significant from trivial harms” and prevents employees from using Title VII to impose “ ‘a general civility code for the American workplace.’ ” White, 548 U.S. at 68, 126 S.Ct. 2405 (quoting Oncale, 523 U.S. at 80, 118 S.Ct. 998). Courts use an objective standard — the “reasonable employee” — to judge whether an alleged act of retaliation was materially adverse, not a subjective standard “based on a ‘plaintiffs personal feelings.’” Daniels, 701 F.3d at 638 (quoting Semsroth v. City of Wichita, 555 F.3d 1182, 1184 (10th Cir. 2009)). Although a retaliatory action must be materially adverse, it does not have to be workplace-related or an “ultimate employment decision[ ].” White, 548 U.S. at 63-64, 67, 126 S.Ct. 2405 (concluding that “Title VII’s substantive provision and its antiretaliation provision are not coterminous” and that “[t]he scope of the antiretaliation provision extends beyond workplace-related or employment-related retaliatory acts and harm”).

Although Title VII’s anti-retaliation provision is broader than its anti-discrimination provision, Plaintiff does not allege additional non-employment-related acts of retaliation. Instead, Plaintiff relies on the same allegedly discriminatory actions set forth in her Title VII gender discrimination action. The Court has already rejected Plaintiffs contentions regarding call-out time, her worker’s compensation claim, her overtime hours, and her acting CPO opportunities. See supra Part A.1. Plaintiff makes no effort to describe how these actions were materially adverse, how they stemmed from her protected conduct, or even that they arose after she engaged in protected opposition to discrimination.16 Plaintiff likewise fails to indicate how the other actions she complains of are “materially adverse” or relate to her protected conduct. For example, Defendant Phillips’s criticism of Plaintiff for allowing her clearwell level to get too low occurred in July of 2009, several months before" Plaintiff filed her grievance or EEOC charge. Additionally, although Plaintiff contends Defendant Phillips sin*1178gled her out for using her cell phone at work17 and not carrying her two-way radio on account of her gender, she does not allege that he did so to retaliate against her for filing a grievance or an EEOC charge.18 What is more, this type of criticism does not rise to the level of seriousness required for an adverse action to be “materially adverse,” as required by the Supreme Court. See, e.g., White, 548 U.S. at 67-70, 126 S.Ct. 2405 (holding “normally petty slights, minor annoyances, and simple lack of good manners” not actionable under Title VII antiretaliation provision because such adverse actions will not deter victims from reporting discrimination). Accordingly, Plaintiff has not established her prima facie case and summary judgment for Defendant City is appropriate.

B. Equal Protection

Count IV of Plaintiffs Complaint alleges that all Defendants “deprived Plaintiff of her constitutional right to equal protection” while “acting under the color of their authority.” (Pl.’s Compl. at 6.) Plaintiffs claim is brought pursuant to 42 U.S.C. § 1983. Because § 1983 does not provide its own statute of limitations for civil rights claims, the two-year limitations period for injuries to personal rights in Oklahoma applies. See Alexander v. Oklahoma, 382 F.3d 1206, 1212 n. 1 (10th Cir. 2004) (citing 12 Okla. Stat. § 95); Garcia v. Wilson, 731 F.2d 640, 651 (10th Cir. 1984). Thus, the Court will consider only those events occurring on or after June 7, 2009.

1. Defendant City

Although municipalities can be sued under § 1983, “a municipality cannot be held liable solely because it employs a tortfeasor,” or on the basis of the doctrine of respondeat superior. Monell v. Dep’t of Soc. Servs. of City of N.Y., 436 U.S. 658, 690, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978); see also Milligan-Plitt v. Bd. of Trs. of Sheridan Cnty. Sch. Dist. No. 2, 523 F.3d 1219, 1223 (10th Cir. 2008). Instead, “ ‘to establish municipal liability, a plaintiff must show 1) the existence of a municipal policy or custom, and 2) that there is a direct causal link between the policy or custom and the injury alleged.’ ” Bryson v. City of Okla. City, 627 F.3d 784, 788 (10th Cir. 2010) (quoting Hinton v. City of Elwood, 997 F.2d 774, 782 (10th Cir. 1993)), cert. denied, - U.S. -, 131 S.Ct. 3030, 180 L.Ed.2d 846 (2011). Plaintiff may use any of the following to establish a municipal policy or custom:

(1) “a formal regulation or policy statement,” (2) an informal custom “amoun[ting] to a “widespread practice that, although not authorized by written law or express municipal policy, is so permanent and well settled as to constitute a custom or usage with the force of law' ”; (3) “the decisions of employees with final policymaking authority”; (4) “the ratification by such final policymakers of the decisions — and the basis for them — of subordinates to whom authority was del*1179egated subject to these policymakers’ review and approval”; or (5) the “failure to adequately train or supervise employees, so long as that failure results from ‘deliberate indifference’ to the injuries that may be caused.”

Id. (quoting Brammer-Hoelter v. Twin Peaks Charter Acad., 602 F.3d 1175, 1189-90 (10th Cir. 2010) (internal citations omitted)).

Defendant City requests summary judgment on Plaintiffs § 1983 claim on the basis that such a claim is more properly pursued against Plaintiffs supervisor, not the City, because the City cannot be held vicariously hable for Defendant Phillips’s actions and Plaintiff has not established a City custom or policy of gender discrimination. In response, Plaintiff does not point to a formal City policy of gender discrimination, a widespread practice of gender discrimination, that Defendant Phillips was an employee with final decision-making authority, that final policymakers ratified Defendant Phillips’s conduct, or that the City failed to train or supervise its employees because of its deliberate indifference to the injuries that could be caused by gender discrimination. Instead, Plaintiff argues that by failing to correct Defendant Phillips’s harassment of Plaintiff, Defendant City acquiesced to Defendant Phillips’s discrimination, making the City liable. Plaintiff provides no supporting authority19 for this statement. Moreover, even if acquiescence were sufficient to subject the City to liability, Plaintiff has not alleged facts demonstrating this type of acquiescence. When the City learned that Defendant Phillips, contrary to City policy, was allegedly harassing a female employee on the basis of her gender, it promptly conducted a thorough investigation of Plaintiffs claims. (Def. City’s Reply, Dkt. No. 68, at 2-4, Ex. 3.) Accordingly, summary judgment for Defendant City is appropriate on Plaintiffs § 1983 claim.

2. Defendant Phillips

a. Gender Discrimination

The elements of a discrimination lawsuit are the same whether brought pursuant to § 1983 or Title VII. See Drake v. City of Fort Collins, 927 F.2d 1156, 1162 (10th Cir. 1991). Under the McDonnell Douglas burden-shifting framework, Plaintiff has the initial burden of establishing a prima facie case of gender-based discrimination, just as with a Title VII action. E.E.O.C. v. PVNF, L.L.C., 487 F.3d 790, 800 (10th Cir. 2007). If Plaintiff meets her *1180burden, Defendant must “articulate a legitimate, nondiscriminatory reason for the adverse action.” Id. Plaintiff must then demonstrate “a genuine issue of material fact as to whether [Defendant’s] proffered reasons are pretextual.” Id. Defendant Phillips concedes that Plaintiff is a member of a protected class and therefore challenges only the second and third elements of Plaintiffs prima facie case — adverse employment action and causation.

First, Defendant Phillips argues that Plaintiff has failed to establish her prima facie case because she has not demonstratr ed that she has suffered an adverse employment action. Plaintiff has not been terminated, demoted, disciplined, or had her salary reduced. (Def. Phillips’s Br., Ex. 16 at 164.) Nor did Defendant Phillips ever rate Plaintiff less than “fully competent” in her annual performance evaluations. (Id., Ex. 16 at 81-90.) Nevertheless, Plaintiff argues that Defendant Phillips took overt employment action against her in two ways: first, by harassing her over minor work-related matters and treating her with hostility, and, second, by denying her the same overtime and acting CPO opportunities as the male employees, thus decreasing her potential earnings. (Pl.’s Resp. to Def. Phillips, Dkt. No. 65, at 1-2, 4-7.)

Plaintiffs § 1988 gender discrimination claim against Defendant Phillips fails for the same reasons that the Court laid out in analyzing her Title VII gender discrimination claim against Defendant City. The Court has already rejected Plaintiffs claims with respect to her overtime and acting CPO opportunities, concluding that the evidence shows that Plaintiff worked more overtime and acting CPO hours than all but one of her male co-workers, rebutting any suggestion of adverse action or gender bias. See supra part A.1. Moreover, the statute of limitations bars this Court from considering many of the actions Plaintiff suggests constitute actionable harassment.20 Those remaining — instructing Plaintiffs supervisors to monitor her work and report any errors, directing Plaintiff to carry her two-way radio at all times, and singling Plaintiff out for her cell phone use21—even if true, are not the type of adverse action that gender discrimination laws are meant to address. See White, 548 U.S. at 67-70, 126 S.Ct. 2405. Accordingly, Defendant Phillips is entitled to summary judgment.

b. Retaliation

Plaintiff has also asserted a retaliation claim against Defendant Phillips.22 To es*1181tablish a prima facie case of retaliation under McDonnell Douglas, Plaintiff must show: “(1) she engaged in protected opposition to ... discrimination; (2) she suffered an adverse employment action; and (3) there is a causal connection between the protected activity and the adverse employment action.” Meiners v. Univ. of Kan., 359 F.3d 1222, 1229 (10th Cir. 2004). Defendant again argues that Plaintiff has not established a prima facie case because she has not demonstrated that Defendant Phillips took a materially adverse action against her with respect to her employment. Although the Court rejects Defendant’s contention that Plaintiff did not suffer an adverse action simply because Defendant Phillips did not terminate, demote, or discipline her, Plaintiffs § 1983 claim against Defendant Phillips fails for the same reasons set forth by this Court in analyzing Plaintiffs Title VII retaliation claim against Defendant City. See supra Part A.3. Plaintiff has not demonstrated that she suffered a materially adverse action. Out of those actions put forward, Plaintiff has not shown any retaliatory motive, whether by temporal proximity or otherwise. Thus, summary judgment for Defendant Phillips is appropriate.

C. Equal Pay Act

Count V of Plaintiffs Complaint alleges a violation of the Equal Pay Act (“EPA”) based on the fact that “Defendants paid other male co-workers more than what they paid Plaintiff notwithstanding that the male co-workers had jobs substantially equal to Plaintiffs job.” (Pl.’s Compl. at 6.) Claims brought pursuant to the Equal Pay Act are subject to a two-year statute of limitations, meaning the Court will only look at actions of the Defendants taking place on or after June 7, 2009. See 42 U.S.C. § 255. For claims based upon the EPA, Plaintiff has the initial burden of “demonstrating that employees of the opposite sex were paid differently for performing substantially equal work.” Mickelson v. New York Life Ins. Co., 460 F.3d 1304, 1311 (10th Cir. 2006). If Plaintiff establishes a prima facie case of discrimination, Defendant City and Defendant Phillips will have the burden of persuasion and must “prove that the wage disparity was justified by one of four permissible reasons.” Id.

Plaintiff has not satisfied her initial burden by providing evidence she received less pay than the City’s male employees who performed substantially equal work. For all time relevant to this action, a controlling collective bargaining agreement has determined Plaintiffs base rate of pay. Plaintiff receives the top pay authorized by the collective bargaining agreement for a plant operator; no plant operator receives a higher rate of pay than Plaintiff. The only times male employees received a higher rate of pay, the City *1182made a determination that the employee in question had been overpaid and required that employee to repay the extra income to the City. Plaintiff argues in response that the EPA covers more than just wage disparity claims. According to Plaintiff, the EPA also provides a remedy to workers denied the opportunity to earn additional income, such as by working overtime or serving as acting CPO, because of their gender. However, Plaintiffs misinterprets the Equal Pay Act. The EPA addresses gender-based disparities in pay for work performed, not disparities in opportunity. Accordingly, both Defendants are entitled to summary judgment on this claim.

D. Tort Claims

1. Defendant City

Plaintiff asserted two negligence claims in her Complaint against Defendant City: (1) infliction of emotional distress23 and (2) negligent supervision, training, and retention. (Pl.’s Comp. at 7-8.) Because the City is a political subdivision of the State of Oklahoma, see 51 Okla. Stat. § 152(11)(a), tort claims against the City must be brought pursuant to the Oklahoma Governmental Tort Claims Act (“GTCA”), 51 Okla. Stat. § 151, et seq. The GTCA provides that claims must be brought and notice must be given within one (1) year of the date the loss occurs. 51 Okla. Stat. § 156(B); see also Slawson v. Bd. of Cnty. Comm’rs of Logan Cnty., 2012 OK 87, ¶ 6, 288 P.3d 533, 534. Plaintiff filed her Notice of Tort Claim on April 28, 2011 (Pl.’s Compl. at 2.) Thus, in evaluating Plaintiffs negligence claims, the Court will only consider events occurring on or after April 28, 2010.

a. Negligent Infliction of Emotional Distress

Plaintiff bases her negligent infliction of emotional distress claim on Defendant City’s failure to intervene and protect Plaintiff from Defendant Phillips’s conduct that was “outrageous in the extreme.” (Pl.’s Resp. to Del City at 28.) To prevail on a negligent infliction of emotional distress claim, Plaintiff must prove: (1) a duty on the part of the City to protect Plaintiff from injury; (2) the City’s failure to perform that duty; and (3) that Plaintiff suffered an injury as a result of Defendant’s failure. Chenoweth, 2010 OK CIV APP 91, ¶ 14, 240 P.3d at 1083 (citing Kraszewski v. Baptist Med. Ctr. of Okla., Inc., 1996 OK 141, ¶ 1, 916 P.2d 241, 243 n. 1). Oklahoma law permits Plaintiff to recover for mental anguish only upon proper proof that the anguish either “is caused by physical suffering” or “inflicts physical suffering.” Ellington v. Coca Cola Bottling Co. of Tulsa, Inc., 1986 OK 11, ¶ 8, 717 P.2d 109, 111; see also Roberts v. Langston Univ., Case No. CIV-10-1378-C, 2011 WL 1194673 at *2 (W.D.Okla. Mar. 30, 2011).24

Defendant first seeks to dismiss Plaintiffs negligent infliction claim under the GTCA. Defendant City argues that if *1183Defendant Phillips harassed Plaintiff, he acted in bad faith, outside the scope of his employment.25 (Def. City’s Br. at 21.) The GTCA provides that the City “shall not be liable ... for any act or omission of an employee acting outside the scope of his employment.” 51 Okla. Stat. § 153(A). However, in a prior discrimination case alleging negligent infliction of emotional distress, this Court recognized that “[b]y definition, negligence claims are based on a lack of malicious or willful conduct and thus there is no allegation that the actor was acting in bad faith.” Roberts, 2011 WL 1194673 at *2. Thus, “[bjeeause Plaintiffs claim for relief, by definition, precludes malicious or bad faith conduct, the alleged wrongs of the individual Defendants necessarily occurred within the scope of their employment.” Id. Accordingly, the GTCA does not bar Plaintiffs claim against the City.

Defendant City next argues that Plaintiffs claim must fail because she did not allege a physical injury, as required by Ellington. (Def. City’s Br. at 23-24.) However, Plaintiff alleged that she “suffered from migraines and stress that affected her work and her ability to sleep” and “also broke her molar because of her grinding her teeth due to the stress of work.” (Pl.’s Resp. to Def. City at 28.) Although Defendant City attempts to refute Plaintiffs testimony about her broken molar (Def. City’s Br. at 24), Plaintiff still has testified that she has suffered migraines, trouble sleeping, and grinding her teeth, all physical manifestations of emotional distress. The Tenth Circuit has recognized difficulty sleeping, crying, and weight gain as evidence of physical harm in a negligent infliction of emotional distress case. Wilson v. Muckala, 303 F.3d 1207, 1213 (10th Cir. 2002). Plaintiff’s alleged physical harm is likewise sufficient for summary judgment purposes.

Alternatively, Defendant City maintains that if Plaintiff alleged a physical injury, the exclusivity provision of the Oklahoma Workers’ Compensation Act, 85 Okla. Stat. § 302(A), bars Plaintiffs negligent infliction claim. Section 302(A) provides: “[t]he liability prescribed in this act shall be exclusive and in place of all other liability of the employer and any of his or her employees, at common law or otherwise, for such injury ... to the employee ... except in the case of an intentional tort.” In a recent case in the Northern District of Oklahoma, the Court held that the plaintiffs emotional distress and digestive problems resulting from his termination arose out of his employment, meaning the exclusivity provision of the Oklahoma Workers’ Compensation Act barred his claim for negligent infliction of emotional distress. Amin v. Flightsafety Int’l, Inc., Case No. 06-CV-568-GKF-PJC, 2009 WL 4729946, at *4-5 (N.D.Okla. Dec. 2, 2009) (“In this case there is quite plainly a connection between plaintiffs termination and the alleged physical injury — stomach discomfort.... Therefore, as a separate and alternative ground for summary adjudication, the court concludes plaintiffs negligence claim for physical injuries is barred by the exclusivity provision of the Oklahoma Workers’ Compensation Act.”). Likewise, the Tenth Circuit affirmed the reliance of the Utah District Court on the Utah Worker’s Compensation Act in dismissing the plaintiffs claim for negligent infliction of emotional distress as manifested in the worsening of his heart condition after his discharge. Gephart v. Delmed, *1184Inc., Case No. 90-4190, 1992 WL 372380, at *2-3 (Tenth Cir. Dec. 10, 1992). This Court agrees with the reasoning of Amin and Gephart and concludes that the exclusivity provision in Oklahoma’s workers’ compensation statutes bars Plaintiffs negligent infliction of emotional distress.26

b. Negligent Training and Retention

In Count VII of her Complaint, Plaintiff alleges that Defendant City breached its duty “to properly supervise and train its employees to refrain from engaging in ... gender harassment, discrimination, and retaliation.” (Pl.’s Compl. at 8.) Oklahoma law recognizes the tort of negligent hiring and retention. N.H. v. Presbyterian Church (U.S.A), 1999 OK 88, ¶ 20, 998 P.2d 592, 600. An employer will be held liable if, at the time of the tortious incident, “the employer had reason to believe that the [tortfeasor-employee] would create an undue risk of harm to others.” Employers are only liable if they had “prior knowledge of the [employee’s] propensity to commit the very harm for which damages are sought,” id., but “knowledge may be imputed to the employer from information obtained by its supervisory employees.” Austin v. Edmond Transit Mgmt., Inc., Case No. CIV-12-324-D, 2013 WL 49710, at *6 (W.D.Okla. Jan. 2, 2013).

Defendant City was aware that Plaintiff had complained of gender discrimination and retaliation as of October 19, 2009, when she filed her union grievance against Defendant Phillips. However, Plaintiffs assertion — that Defendant City took no action after learning of potential discrimination — is inaccurate. When Defendant City learned of Plaintiffs claims of gender discrimination, it referred the matter to two investigators who looked into Plaintiffs claims and submitted a thirteen-page report. (Def. City’s Reply at 2-4, Ex. 3.) The investigators’ conclusions were that there was insufficient evidence to support Plaintiffs claim that she had been denied overtime opportunities and “insufficient evidence to support any claim of disparate treatment in other aspects of her employment environment.” (Id., Ex. 3 at 12.) Thus, the investigators recommended no administrative action be taken. (Id., Ex. 3 at 13.) Although Plaintiff refers to the City’s discrimination investigation as “ineffectual,” merely because the investigation came to a conclusion contrary to her position does not mean that her claims were not thoroughly investigated. Based on the City’s investigation into Plaintiffs claims, the City did not breach its duty to Plaintiff and summary judgment is appropriate.

2. Defendant Phillips

Although Plaintiffs Complaint asserted that .Count VI “goes against all Defendants,” in her response to Defendant’s motion Plaintiff states that she “did not allege infliction of emotional distress against Defendant Phillips.” (Pl.’s Resp. to Def. Phillips at 15.) Thus, Defendant Phillips’s Motion for Summary Judgment is granted.

IV. CONCLUSION

Defendant City and Defendant Phillips have established that they are entitled to summary judgment as a matter of law with respect to the claims raised in Plaintiffs Complaint. Accordingly, Motion for Summary Judgment of Defendant, Dennis Phillips (Dkt. No. 53) and Defendant City’s *1185Motion for Summary Judgment (Dkt. No. 56) are hereby GRANTED.
