Can You Fire an Employee on FMLA Leave?

DefensibleHR.ai Compliance Team · Updated July 2026

Short version: Yes — but only for a reason that has nothing to do with the leave. FMLA doesn't make an employee on leave more fireable-proof than they'd be at their desk, but it doesn't make them less protected either. The catch is timing: fire someone during or right after protected leave and the law effectively assumes the leave was the reason. Your entire defense is documentation that existed before the leave did.

The rule underneath the question

The Family and Medical Leave Act gives eligible employees up to 12 weeks of job-protected leave and the right to return to the same or an equivalent position. It does not freeze them in amber. An employee on FMLA leave "has no greater right to reinstatement than if they had been continuously employed" — so if something independent of the leave would have ended their employment anyway, it still can.

That's the entire legal test, and it's deceptively simple: would this termination be happening, on this timeline, if the employee had never taken the leave? If you can prove yes, with evidence, you're likely on solid ground. If the honest answer is "well, the leave is what brought the issue to a head," you're looking at an interference claim.

Two ways it becomes a lawsuit

Interference is denying or discouraging FMLA rights — including terminating an employee specifically to avoid having to reinstate them. Retaliation is punishing someone because they took leave. A termination during or immediately after leave can trigger both at once, and the plaintiff doesn't need a smoking gun — the timing alone gets them past the early stages and shifts the practical burden onto you to produce the independent reason.

The pattern plaintiff's attorneys look for: a clean personnel file, an FMLA request, and then — suddenly — a performance problem and a termination. Even when the performance problem is completely real, a paper trail that starts after the leave request reads as pretext. The fix is never retroactive.

Frequently asked questions

Can you legally fire an employee who is on FMLA leave?

Yes, but only for a reason entirely unrelated to the leave. If the employee would have been terminated regardless — a documented performance problem predating the leave, or a genuine layoff of their role — it can be lawful. The leave can never be a factor, and the timing means you carry the burden of proving it wasn't.

What's the difference between FMLA interference and retaliation?

Interference is denying, discouraging, or failing to restore FMLA rights — including firing to avoid reinstatement. Retaliation is adverse action because someone used leave. A termination near leave can trigger both, which is why pre-existing documentation matters so much.

Does an employee on FMLA leave have to be reinstated?

Generally yes — to the same or an equivalent position. Exceptions: they'd have lost the job anyway (bona fide layoff), narrowly-defined "key employees," or they can't perform an essential function (which triggers ADA analysis).

Can I include someone on FMLA leave in a layoff?

Yes, if the layoff genuinely eliminates their position independent of the leave and the selection criteria were applied neutrally. It's a high-scrutiny situation — document that the decision would have happened anyway.

What if I discover misconduct during the leave?

Courts recognize an "honest belief" defense — you can act on a genuine, reasonably-held belief of misconduct or leave fraud even during leave, if it's based on real evidence gathered through a fair process.
