The Family and Medical Leave Act (FMLA) requires covered employers to provide qualifying employees with a minimum amount of unpaid leave for certain reasons. It also prohibits employers from interfering with employees’ use of authorized leave, discriminating based on the use of leave time, or retaliating against an employee for using leave. The Third Circuit Court of Appeals, whose jurisdiction includes New Jersey employment disputes involving federal law, recently ruled on a case alleging retaliation under the FMLA. It found that the district court should have given the jury an instruction regarding the “mixed-motive” theory of liability, which shifts the burden of proof to the defendant if a plaintiff demonstrates that their “use of FMLA leave was a negative factor in the employer’s adverse employment decision.” Egan v. Del. River Port Auth., 851 F.3d 263, 267 (3rd Cir. 2017).
Employees who meet a minimum requirement for number of hours worked during the preceding 12-month period are eligible for up to 12 weeks of unpaid leave under the FMLA. 29 U.S.C. §§ 2611(2), 2612(a)(1). This only applies, however, if the employer has at least 50 employees. Id. at § 2611(4). Many workers do not qualify for FMLA leave because their employer is not big enough, or they have not worked for the employer long enough to become eligible. The FMLA provides numerous protections to help ensure that employees who are able to accrue leave are able to use it. This includes a prohibition on retaliating against an employee who uses or attempts to use leave to which they are entitled. Id. at § 2615(a)(1), 29 C.F.R. § 825.220(c).
Courts have identified two general theories for discrimination and retaliation claims: pretext and mixed-motive. In a pretext claim, a plaintiff asserts that an employer’s stated reason for an adverse action is false and is merely a pretext for an unlawful motive. A mixed-motive theory alleges that an employer had “both legitimate and illegitimate reasons” for the adverse action. Egan, 851 F.3d at 268 n. 1. The plaintiff must show that the “exercise of FMLA rights was ‘a negative factor’ in the employer’s employment decision.” Id.
