Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.

. The Rehabilitation Act states, in part, "No otherwise qualified individual with a disability in the United States, as defined in section 705(20) of this title, shall, solely by reason of her or his disability!)] be subjected to discrimination under any program or activity receiving Federal financial assistance or ... by the United States Postal Service.” 29 U.S.C. § 794(a). The statute tracks the language of the Americans with Disabilities Act in determining whether a violation has occurred with regard to an employment decision. 29 U.S.C. § 794(d).

. Couatre displayed symptoms of depression following complications arising from the unique and substantial health problems of his daughter. After Richard Palisi became postmaster at Clouatre's station, Palisi asked his employees to take on additional workloads. Clouatre refused. Palisi and other supervisors cited Clouatre for numerous technical violations concerning the delivery of his mail; they rarely, if ever, cited other employees for similar violations. Clouatre complained of increased stress, his behavior became erratic, and he requested assistance for his deliveries. He eventually sought psychiatric treatment.

. To establish a prima facie claim of intentional discrimination, a plaintiff must show " '(1) he or she suffers from a disability; ,(2) he or she is qualified for the job; (3) he or she was subject to an adverse employment action; and (4) he or she was replaced by a non-disabled person or was treated less favorably than non-disabled employees.'" Burch v. Coca-Cola Co., 119 F.3d 305, 320 (5th Cir. 1997) (quoting Daigle v. Liberty Life Ins. Co., 70 F.3d 394, 396 (5th Cir. 1995)). As part of proving he is a “qualified individual,” a disabled plaintiff must illustrate that, "with or without reasonable accommodation, [he] can perform the essential functions of the employment position [he] holds or desires.” 42 U.S.C. § 12111(8).

. The court, arguendo, assumed that a combination of Clouatre's increasingly odd behavior and his requests to management to “back off” sufficed to alert his supervisors that something warranted their attention. See Taylor v. Phoenixville Sch. Dist., 184 F.3d 296, 313-14 (3d Cir. 1999). Such odd behavior included switching delivery routes on a frequent basis, requesting help for routine deliveries, and substantially underperforming on the amount of mail delivered in a shift. We do not express an opinion as to whether one may notify an employer of a disability merely through actions and informal statements rather than through a more formalized declaration.

. “Where the disability, resulting limitations, and necessary reasonable accommodations, are not ... apparent to the employer, as is often the case when mental disabilities are involved, the initial burden rests primarily upon the employee, or his health-care provider, to specifically identify the disability ... and to suggest the reasonable accommodations.” Taylor v. Principal Fin. Group, 93 F.3d 155, 165 (5th Cir. 1996). Such a notification triggers a duty on the part of the employer “to participate in the interactive process of determining” an accommodation. Id.

. In certain instances, the employee's disability will be such that the employer "may have an extra duty to explore the employee's condition.” Loulseged v. Akzo Nobel, Inc., 178 F.3d 731, 736 n. 5 (5th Cir. 1999). Here, the court determined that the Postal Service, by conducting a fitness-for-duty examination of Clouatre, sufficiently explored his condition to satisfy whatever duty it may have owed.

. Shortly after Clouatre's termination, a psychiatrist who treated him diagnosed a disabling medication condition that precluded "useful service" in the Postal Service. Eventually, in interviews with a psychiatrist, Clouatre made threatening statements against some of his former supervisors.

. We review the court's findings of fact for clear error and its legal conclusions de novo. Coggin v. Longview Indep. Sch. Dist., 289 F.3d 326, 330 (5th Cir. 2002).

. The court stated that "[m]uch of the behavior directed toward [Clouatre] was unjust and inhumane.... This, however, does not bring plaintiff under the protection of the Rehabilitation Act.” Because he is a federal employee, Clouatre may not sue under the Federal Tort Claims Act or similar state tort statutes. See, e.g., Bennett v. Barnett, 210 F.3d 272, 277 (5th Cir. 2000) (holding that a postal employee’s emotional distress claims brought against the Postal Service, under the Federal Tort Claims Act, were preempted by the Federal Employees’ Compensation Act); Rollins v. Marsh, 937 F.2d 134, 138-40 (5th Cir. 1991) (holding that Civil Service Reform Act precluded suit under Federal Tort Claims Act).
