Can You Terminate an Employee on FMLA Leave?
Yes — but only for reasons that would have applied anyway, and the burden of proving that is yours. The reinstatement right, its limits under 29 CFR 825.216, and the retaliation trap, verified against the regulations.

The short answer
Yes — an employee on FMLA leave can lawfully be terminated, but only for a reason independent of the leave, and the employer carries the burden of proving it. FMLA leave is not a shield against a layoff that would have included the employee anyway, a position elimination, or misconduct discovered on its own. It is an absolute shield against being terminated because of the leave — and the closer the termination sits to the leave request, the more the paperwork has to carry.
What the reinstatement right covers
An employee returning from FMLA leave is entitled to the same or an equivalent position — substantially similar duties, pay, benefits, shift, worksite, and status. Equivalent means genuinely equivalent: same or geographically proximate worksite, same or equivalent schedule, and the same opportunity for bonuses and profit-sharing. What the right does not cover is anything the employee would have lost anyway: if the worksite closed, the shift was eliminated, or the whole department was restructured, the returning employee stands exactly where continuous employment would have put them — no worse, no better.
When termination during leave is lawful
The burden of proof is yours
The regulation puts it in one sentence: "An employer must be able to show that an employee would not otherwise have been employed at the time reinstatement is requested in order to deny restoration to employment." In practice that means the layoff selection matrix, the restructuring memo, or the investigation file must exist and must predate — or be provably independent of — the leave. A reason assembled after the leave request reads as pretext, and juries are invited to read it that way.
The retaliation trap
Even a defensible termination can generate a second, separate claim. 29 CFR 825.220 prohibits interfering with FMLA rights, discharging or discriminating against anyone for opposing unlawful practices, and counting FMLA leave against an employee in disciplinary or attendance systems. The classic loss pattern isn't a fabricated reason — it's a real reason applied only to the person who took leave, or a no-fault attendance policy that quietly counted FMLA days. Audit the timing, the comparators, and the attendance math before the meeting, not after the complaint.
