ORDER

Introduction

Before me,1 in this matter wherein Maria Ornelas, Victory Vergara, Rito Cruz, and Jesus Martinez assert that Los Arrie-ros, Chen Los Arrieros Inc., Xiu Yan Dong, and Yong Xiu Chen violated several federal and state provisions2 during their *965employment of the Plaintiffs, are cross-motions for full summary judgment.3 The court has jurisdiction over federal claims under 28 U.S.C. § 1331, with supplemental jurisdiction over related state law claims under 28 U.S.C. § 1367. The relevant parties have responded in opposition to the various summary judgment motions.4 For the reasons that follow, the Defendants’ motion for summary judgment will be denied and the plaintiffs’ motion for summary judgment will be granted in part and denied in part.

Analysis

A. Standard of Review

1. Summary Judgment

Summary judgment is appropriate where the court is satisfied “that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.”17 The burden of showing the absence of any such “genuine issue” rests with the moving party:

[A] party seeking summary judgment always bears the initial responsibility of informing the district court of the basis for its motion, and identifying those portions of ‘the pleadings, depositions answers to interrogatories, and admissions on file, together with affidavits, if any,’ which it believes demonstrates the absence of a genuine issue of material fact.18

A fact is “material” only if its resolution will affect the outcome of the lawsuit.19 Determination of whether a factual issue is “genuine” requires consideration of the applicable evidentiary standards.20 The court will view the summary judgment motion “in the light most favorable to the party opposing the motion.”21

Summary judgment should be granted if a party who bears the burden of proof at trial does not establish an essential element of his case.22 Accordingly, “[t]he mere existence of a scintilla of evidence in support of the plaintiffs position will be insufficient; there must be evidence on which the jury could reasonably find for the plaintiff.”23 Moreover, if the evidence presented is “merely colorable” and not “significantly probative,” the court may decide the legal issue and grant sum*967mary judgment.24 In most civil cases involving summary judgment, the court must decide “whether reasonable jurors could find by a preponderance of the evidence that the [non-moving party] is entitled to a verdict.”25 However, if the non-moving party faces a heightened burden of proof, such as clear and convincing evidence, it must show that it can produce evidence which, if believed, will meet the higher standard.26

Once the moving party has satisfied its burden of proof, the burden then shifts to the nonmover.27 The nonmoving party may not simply rely on its pleadings, but must “produce evidence that results in a conflict of material fact to be solved by a jury.”28 The text of Fed. R. Civ. P. 56(e) states:

When a motion for summary judgment is made and supported as provided in this rule, an adverse party may not rest upon the mere allegations or denials of his pleading, but his response, by affidavits or as otherwise provided in this rule, must set forth specific facts showing that there is a genuine issue for trial.

“In other words, the movant can challenge the opposing party to ‘put up or shut up’ on a critical issue.”29

' [7,8] Though parties must produce evidence in support of and in opposition to a motion for summary judgment, not all types of evidence are permissible. The Sixth Circuit has concurred that “ ‘it is well settled that only admissible evidence may be considered by the trial court in ruling on a motion for summary judgment.’ ”30 Rule 56(e) also has certain, more specific requirements:

[it] requires that affidavits used for summary judgment purposes be made on the basis of personal knowledge, set forth admissible evidence, and show that the affiant is competent to testify. Rule 56(e) further requires the party to attach sworn or certified copies to all documents referred to in the affidavit. Furthermore, hearsay evidence cannot be considered on a motion for summary judgment.31

However, the district court may consider evidence not meeting this standard unless the opposing party affirmatively raises the issue of the defect. The burden is on the opposing party to object to the improper evidence; failure to object constitutes a waiver.

If a party fails to object before the district court to the affidavits or eviden-tiary materials submitted by the other party in support of its position on summary judgment, any objections to the district court’s consideration of such materials are deemed to have been waived, and [the Sixth Circuit] will review such objections only to avoid a gross miscarriage of justice.32

As a general matter, the judge considering a motion for summary judg*968ment is to examine “[o]nly disputes over facts that might affect the outcome of the suit under governing law.”33 The court will not consider non-material facts, nor will it weigh material evidence to determine the truth of the matter.34 The judge’s sole function is to determine whether there is a genuine factual issue for trial; this does not exist unless “there is sufficient evidence favoring the nonmoving party for a jury to return a verdict for that party.”35

In sum, proper summary judgment analysis entails:

the threshold inquiry of determining whether there is the need for a trial-whether, in other words, there are any genuine factual issues that properly can be resolved only by a finder of fact because they may reasonably be resolved in favor of either party.36

B. Application of Standard

1. Federal FLSA Claims

a. Defendants’ Motion for Summary Judgment on Federal Claims

For the reasons that follow the defendants’ motion for summary judgment on claims two, five, seven, and eight will be denied because of disputed material facts.

The defendants claim that Los Arrieros is not subject to the regulation of the Fair Labor Standards Act because they are not covered by the enterprise provision.37 This provision applies to businesses that: (1) has employees engaged in commerce or in the production of goods for commerce, or that has employees handling, selling, or otherwise working on goods or materials that have been moved in or produced for commerce by any person; and (2) is an enterprise whose annual gross volume of sales made or business done is not less than $500,000.38

The defendants’ motion fails because there is a dispute as to the total yearly income of the defendants’ restaurant.39 In support of their assertions, the defendants provide unsigned, self-prepared tax returns for 2009-2014, each indicating that gross revenue is under $500,OOO.40 But, there is no affidavit stating their authenticity such as would make the evidence proper for consideration here in this court, nor are the returns signed.41 In addition, each plaintiff employed as a server submitted an affidavit testifying that each consistently saw daily receipts that typically range from $1500-$3000.42 They also submitted photo evidence of multiple daily receipts-each showing over $2000 in revenue.43 There is evidence, in the form of audio recordings, that the defendants had attempted to falsify records during the plaintiffs’ period of employment,44 which sup*969ports the plaintiffs’ assertion that the gross income of Los Arrieros is higher than the tax returns indicate. An addition of a signature on the defendants’ tax return would make it admissible as evidence and therefore this court finds that there are material facts in dispute.45

Accordingly, the motion for summary judgment on claims two, five, seven, and eight is denied because of disputed material facts.

As part of the motion for summary judgment on the federal claims, the defendants have moved to dismiss the plaintiffs’ state law claims under 28 U.S.C. § 1367(C).46 That section gives this Court discretion to decline the exercise of supplemental jurisdiction over state law claims if “the district court dismisses all claims over which it has original jurisdiction.”47 Because I have denied the defendants’ motion for summary judgment as to the federal claims, consideration of declining supplemental jurisdiction is premature. I, therefore, also deny the defendants’ motion to dismiss the state claims for want of subject matter jurisdiction.

b. Plaintiffs Motion for Summary Judgment on Federal Claims

The plaintiffs’ motion for summary judgment on claims two, five, seven, and eight is denied because of disputed material facts. Los Arrieros concedes that they meet the first prong of the enterprise provision, but in order for a business to be subject to FLSA, it must meet both prongs.48 As analyzed above, the enterprise provision’s applicability to Los Arrie-ros and it’s management has disputed material facts directly related to the income requirement of the second prong.

The plaintiffs also claim that Cruz, the cook, does not fall into a category exempt from the FLSA overtime pay requirement.49 In accordance with the facts laid out in his affidavit50 and because the defendants do not challenge this assertion, Cruz would be due overtime wages under FLSA if the employer is subject to them.

Accordingly, the motion for summary judgment on claims two, five seven, and eight is denied because of disputed material facts.

2. State Law Claims

a. Plaintiff's ’ Motion for Summary Judgment on State Law Claims

Plaintiffs’ motion for summary judgment on claims one, three, four, six, nine, and ten are granted. There is no dispute that the defendants meet the income requirements to be subject to state of Ohio claims.51 The defendants conceded they were employers of the plaintiffs in their interrogatories,52 thus they are personally *970liable53 for the defendant’s claims.54

i. Minimum Wage and Overtime Payments

Claims one, four, and six directly involve the failure to pay minimum wages and overtime wages. The plaintiffs established in their affidavits that they were employed for over 40 hours a week, yet they did not receive overtime wages.55 Plaintiffs Ornelas, Vergara, and Martinez were not paid any wages at all and were only compensated with earned tips.56 Cruz was paid a weekly wage of $400 in cash, but was not paid overtime.57 The defendants counter by arguing that the plaintiffs request for W-2’s indicated that they were receiving wages.58 The defendants did not provide any affidavits indicating that the plaintiffs were fairly paid or copies of W-2’s for the time period in dispute.59 The employment records that the defendants provided did not include any affidavits attesting to their authenticity and show only a small fraction of the time period plaintiffs worked for them.60

Accordingly, because the defendants fail to show a dispute as to the material facts, even when viewed in the light most favorable to the nonmoving party, summary judgment on claims one, four, and six is granted to the plaintiffs.

ii. Tip Provision

Claim three is an alleged violation of Ohio Constitution, Article II, Section 34a regarding tip provisions. Tipped employees may receive wages of not less than half of the minimum wage rate if the wages and tips combined equal or surpass the minimum wage rate.61 Employers are able to receive a tip provision from their employees, but only if the employees tips and wages still surpass the minimum wage rate.62 It was established above that the servers were paid less than minimum wage and therefore the defendants could not claim a tip provision.

Accordingly, the plaintiffs’ motion for summary judgment on claim three is granted.

Hi. Failure to Tender Pay by Regular Payday .

O.R.C. § 4113.15 requires that employers pay their employees within 30 days of when payments are due.63 In claim *971nine, plaintiffs claim the defendants failed to comply with this provision. As established above, the failure to pay wages and overtime wages to the plaintiffs clearly results in a violation of this section. In addition, the defendants do not contest the facts established by the plaintiffs regarding payment dates.

Accordingly, summary judgment on claim nine is granted to the plaintiffs.

iv. Failure to Maintain Wage and Hour Records

Article II, Section 34a of the Ohio Constitution requires employers to maintain wage and hour records. The plaintiffs provided estimated work schedules in their affidavits.64 The defendants provided employment documentation showing time cards, with nothing verifying the authenticity.65 The plaintiffs stated in their affidavits that they were forced to sign false time cards,66 in addition to providing a recording of a defendant instructing plaintiffs to lie about their work hours.67 The defendants provide no evidence of wage records. The defendants have not contested the plaintiffs’ claim with any additional evidence. The defendants fail to provide evidence to dispute the material facts asserted by the plaintiffs.

Accordingly, the plaintiffs motion for summary judgment on claim ten is granted.

b. Defendants’ Motion for Summary Judgment on State Law Claims

As analyzed above, defendants’ motion for summary judgment on claims one, three, four, six, nine, and ten is denied.

Conclusion

The defendants motion for summary judgment68 is denied in full. The plaintiffs motion for summary judgment69 is granted on claims one, three, four, six, nine, and ten. The plaintiffs motion for summary judgment is denied on claims two, five, seven, and eight because of disputed material facts.

IT IS SO ORDERED.
