Charles Green appeals the district court’s order granting his employer’s motion for summary judgment on Green’s claims of discrimination and retaliation under the Americans with Disabilities Act and the Family and Medical Leave Act. Green also appeals the dismissal without prejudice of his pendant state law claims. For the following reasons, we affirm the decision of the district court.

BACKGROUND

The defendant, Burton Rubber Processing, Inc.1 (“Burton Rubber”) employed the plaintiff, Charles Butch Green (“Green”), as a lab technician at its plant in Jonesborough, Tennessee. Green suffered from mental illness and frequently missed work because of his illness. Because of his inability to handle stress, he made numerous *468requests for leave under the Family and Medical Leave Act (FMLA). Burton Rubber’s record in dealing with those requests prior to the termination of Green’s employment leaves a lot to be desired, but the record demonstrates that Green was able to obtain the leave to which he was entitled, albeit with some difficulty, and these requests for FMLA leave are not the subject of this appeal.

The nature of Burton Rubber’s business required that its employees work more than forty hours per week; the required overtime included weekends. Green obtained a letter from his psychiatrist advising that Green should be restricted to a work week of forty hours with weekends off. Burton Rubber accommodated the forty-hour restriction, but was not able always to accommodate the no-weekend restriction. Green then obtained a new letter from the psychiatrist, advising that Green’s work week should not exceed forty hours, and that out of every seven-day work week, he should have two consecutive days off.

This lawsuit arises out of the course of events that followed a meeting Green had with his supervisors during which he received a copy of his new work schedule. The schedule split his work week so that he would have to work some weekends in order to reach forty hours per week. Green angrily questioned this schedule. One of Green’s supervisors informed him that he (the supervisor) “had been told to break up [Green’s] work week.”

Green became very upset and following this meeting he met with his therapist and confided that he had had thoughts of shooting his supervisors. On his therapist’s advice, he checked himself into Woodridge Hospital. The evidence demonstrates that Green was visibly enraged and told doctors and nurses there that he was having thoughts of killing three of his supervisors. Green’s wife had reported that he was “pacing the floors and talking to himself,” and that “he was very agitated and that he voiced a desire to kill all of his employers.” The hospital was aware that Green owned several guns.

Unsatisfied with the treatment he was receiving at the hospital. Green left against his doctor’s advice. He did not tell anyone at the hospital where he was going. A nurse practitioner at the hospital called Burton Rubber to inform a manager or supervisor of Green’s threats. When Green’s supervisors were advised of the threats, they called Woodridge Hospital in an attempt to confirm the validity of the information. Hospital personnel refused to discuss the matter, but arranged to have one of the doctors call Burton Rubber. That doctor advised the Burton Rubber supervisors that he was breaching patient confidentiality requirements because he had a duty to notify them that Green had said he “wanted to kill the 3 supervisors who had confronted him that morning.” The doctor recommended calling the police, which the supervisors did. They also obtained a restraining order against Green.

Green came to work the following day. He claims that he was planning to request FMLA leave for four days. His supervisors asked him to leave the premises, and Green left without any confrontation. Two days later, Burton Rubber sent Green a letter terminating his employment. The letter stated that the company had no choice but to terminate Green because of his threats of physical violence against company employees.

Subsequently, Green filed this action against Burton Rubber in federal district court, alleging that Burton Rubber had violated his rights under the American with Disabilities Act (ADA) by engaging in discriminatory and retaliatory conduct because of his psychological disability, refusing to accommodate his psychological dis*469ability, and discharging him because of his psychological disability. Green further claimed that Burton Rubber had violated his rights under the FMLA by denying him leave for his mental health condition and by discharging him in retaliation for his assertion of his rights pursuant to FMLA. Finally, Green brought state law-claims of handicap discrimination and retaliation under the Tennessee Human Rights Act and the Tennessee Public Protection Act.

Burton Rubber moved for summary judgment. The district court granted the motion. The court held that Green had failed to provide evidence that he was “qualified,” a necessary element of a discrimination claim under the ADA. The ADA protects only “otherwise qualified” employees. An employee who threatens other employees is not qualified, and the undisputed evidence established that Green had made threats against his supervisors. Because Green was not qualified for the job, Burton Rubber did not have to “reasonably accommodate” him under the ADA. The district court also stated that Burton Rubber was allowed to fire Green for unacceptable behavior, i.e., making threats, and that the fact that the behavior was precipitated by mental illness does not present an ADA issue. Regarding Green’s FMLA claims, the district court held that although Green had established a prima facie case, he failed to demonstrate that Burton Rubber’s legitimate, nondiseriminatory reason for terminating him-Green’s threats against the supervisors-was pretextual. The district court dismissed Green’s state law claims without prejudice. Green timely appealed.

ANALYSIS

A. Standard of Review

We review de novo a district court’s grant of summary judgment, using the same standard under Rule 56(c) used by the district court. Williams v. Mehra, 186 F.3d 685, 689 (6th Cir. 1999) (en banc). Summary judgment is proper if “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show 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.” Fed. R. Civ. P. 56(c) (West 2001). Like the district court, we must view the evidence, all facts, and any inferences that may be drawn from the facts in the light most favorable to the nonmoving party. Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986). To withstand summary judgment, the non-movant must show sufficient evidence to create a genuine issue of material fact. Klepper v. First Am. Bank, 916 F.2d 337, 342 (6th Cir. 1990). A mere scintilla of evidence is insufficient; “there must be evidence on which the jury could reasonably find for the [non-movant].” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 252, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). Entry of summary judgment is appropriate “against a party who fails to make a showing sufficient to establish the existence of an element essential to that party’s case, and on which that party will bear the burden of proof at trial.” Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986).

B. Americans with Disabilities Act

To succeed on a claim of discrimination under the ADA, Green must show that he (1) is an individual with a disability; (2) is otherwise qualified to perform the job requirements, with or without reasonable accommodation; and (3) was discharged solely on account of the disability. Walsh v. United Parcel Serv., 201 F.3d 718, 724 (6th Cir. 2000). We agree with the district court that Green failed to demonstrate that he was “otherwise qualified” for his job.

*470The ADA defines a “qualified individual with a disability” as an “individual with a disability who, with or without reasonable accommodation, can perform the essential functions of the employment position that such individual holds or desires.” 42 U.S.C. § 12111(8). This definition is qualified by the requirement that an employee not “pose a direct threat to the health or safety of other individuals in the workplace.” 42 U.S.C. § 12113(b). A direct threat is “a significant risk to the health or safety of others that cannot be eliminated by reasonable accommodation.” 42 U.S.C. § 12111(3). Assessment of the significance of the risk involves four factors: (1) duration of risk; (2) nature and severity of potential harm; (3) likelihood that potential harm will occur; and (4) imminence of potential harm. 29 C.F.R. § 1630.2(r).

The Seventh Circuit has held that the ADA does not require an employer to retain a potentially violent employee because “[s]uch a requirement would place the employer on a razor’s-edge-in jeopardy of violating the Act if it fired such an employee, yet in jeopardy of being deemed negligent if it retained him and he hurt someone.” Palmer v. Cir. Court of Cook County, 117 F.3d 351, 352 (7th Cir. 1997). The Palmer court made it clear that “[i]f an employer fires an employee because of the employee’s unacceptable behavior, the fact that the behavior was precipitated by a mental illness does not present an issue under the [ADA].” Id. And this circuit has followed Palmer, holding that while the ADA protects qualified employees, “threatening other employees disqualifies” an employee from a job. Sullivan v. River Valley Sch. Dist., 197 F.3d 804, 813 (6th Cir. 1999) (citing Palmer, 117 F.3d at 352).2 We agree with the Seventh Circuit that employees who threaten violent acts cannot be reasonably accommodated, and the ADA’s duty to accommodate does not run in favor of those employees. Palmer, 117 F.3d at 353.

The material facts regarding Green’s threats are not in dispute. Green admitted himself to Woodridge Hospital following his meeting with his supervisors. He informed his wife, his therapist, his physician, and hospital personnel that he had thoughts of killing his supervisors. He left the hospital against the doctor’s advice and without his approval. The hospital staff notified Burton Rubber of Green’s threats. Once notified, Burton Rubber investigated the validity of the information and received confirmation from the hospital that the threats had been made. The doctor even recommended a call to the police. Because Burton Rubber did not know where Green was or what his mental condition was at that point, the company called the police. When Green came to work the following day, his supervisors did not know what to expect, and they were apprehensive about his potential for violence. The company also took the precaution of obtaining a restraining order against Green.

We find the principles established in Palmer, and cited in Sullivan, directly ap*471plieable here. We hold that Green’s threats of violence threatened the safety of Burton Rubber’s employees; that when he made those threats, Green disqualified himself from his job at Burton Rubber and from any protection under the ADA. We refuse to place Burton Rubber in the tenuous position of either violating the ADA or retaining a potentially violent employee. Accordingly, we conclude that Burton Rubber lawfully and legitimately terminated Green’s employment.

Because we conclude that Green was terminated because of his threats of violence, we also conclude that he cannot establish a prima facie case of retaliatory discharge under the ADA. Accordingly, we affirm the district court’s grant of summary judgment regarding Green’s ADA claims.

C. Family and Medical Leave Act

Green claims that he intended to request four days of FMLA leave when he returned to work the day following the threats. He contends that Burton Rubber interfered with the exercise of his FMLA rights pursuant to 29 U.S.C. § 2615(a)(1)3 when it refused to grant him leave for his most recent struggle with his mental health. He acknowledges in his appellate brief, however, that his right to FMLA leave is contingent upon a ruling that he was discharged in violation of the ADA. We have held his discharge did not violate the ADA. The FMLA grants benefits to employees. 29 U.S.C. § 2612(a)(1) (“Subject to section 2613 of this title, an eligible employee shall be entitled to a total of 12 workweeks of leave ...” (italics added)). Once Green was discharged, he was no longer an employee, and he was thus not entitled to leave under the FMLA. See Brohm v. JH Properties, Inc., 149 F.3d 517, 523 (6th Cir. 1998).

For the foregoing reasons, rather than on the reasoning of the district court, we affirm the district court’s grant of summary judgment to Burton Rubber on Green’s FMLA claims.

CONCLUSION

Accordingly, we AFFIRM the order of the district court granting summary judgment to Burton Rubber on the Green’s Americans with Disabilities Act and Family and Medical Leave Act claims. Because no federal claims remain, we also AFFIRM the district court’s dismissal without prejudice of Green’s pendent state law claims.
