It is illegal under federal law for an employer to fire you because you are pregnant, because you requested or took pregnancy-related leave, or because you needed a reasonable accommodation for pregnancy. At the same time, being pregnant or on leave does not make you immune from a layoff or termination that would have happened anyway for a lawful, unrelated reason. The legal question is almost always about the employer's true motive and whether they followed the law on leave and accommodations.
Because the answer turns on facts and timing, this article walks through the federal baseline, where state law usually adds more protection, and the concrete steps to protect yourself if you think your job is at risk.
The federal laws that protect you
Pregnancy Discrimination Act (PDA)
The PDA amended Title VII of the Civil Rights Act and is enforced by the U.S. Equal Employment Opportunity Commission (EEOC). It makes it illegal for a covered employer to fire, demote, refuse to hire, or otherwise discriminate against you because of pregnancy, childbirth, or related medical conditions. Under the PDA, your employer must treat pregnancy-related limitations the same way it treats other employees who are similar in their ability or inability to work. The PDA generally applies to employers with 15 or more employees.
Pregnant Workers Fairness Act (PWFA)
The PWFA, also enforced by the EEOC, requires covered employers (again, generally 15 or more employees) to provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions, unless doing so would cause an undue hardship. Accommodations can include things like more frequent breaks, a stool to sit on, light duty, time off for appointments or recovery, or a temporary change in schedule. Importantly, an employer cannot force you onto unpaid leave if another reasonable accommodation would let you keep working, and it cannot retaliate against you for asking.
Family and Medical Leave Act (FMLA)
The FMLA, enforced by the U.S. Department of Labor, Wage and Hour Division, gives eligible employees up to 12 weeks of unpaid, job-protected leave in a 12-month period for the birth of a child and to bond with a newborn, as well as for a serious health condition (which can include pregnancy complications). "Job-protected" means that, in most cases, you are entitled to return to the same or an equivalent position with the same pay and benefits. FMLA leave is unpaid at the federal level, though you may be allowed or required to use accrued paid time off.
Not everyone is covered. To be eligible, you generally must (1) work for an employer with 50 or more employees within a 75-mile radius, (2) have worked there at least 12 months, and (3) have worked at least 1,250 hours in the prior 12 months. If you do not meet these thresholds, you may still be protected by the PDA, the PWFA, the ADA, or a more generous state law.
Americans with Disabilities Act (ADA)
Pregnancy itself is not a disability, but pregnancy-related conditions (such as gestational diabetes, preeclampsia, or complications requiring bed rest) can qualify as disabilities under the ADA, which is enforced by the EEOC. That can entitle you to reasonable accommodations and protection from discrimination separately from the PWFA.
So can you actually be fired?
Yes, but only for a lawful reason unrelated to your pregnancy or leave. An employer can still discipline or terminate a pregnant employee or someone on leave for documented poor performance, a company-wide layoff, position elimination, or serious misconduct, provided the same standards are applied to everyone and the real reason is not the pregnancy.
What makes a firing illegal is when pregnancy, a leave request, or an accommodation request is a motivating factor. Red flags that suggest unlawful motive include:
- You were fired or written up shortly after announcing your pregnancy or requesting leave, with no prior performance problems.
- Your performance reviews were good until you disclosed your pregnancy.
- You were replaced by someone less qualified, or your "eliminated" position was quietly refilled.
- A manager made comments about your commitment, your reliability, "calling in sick," or how you would manage work after the baby.
- You were denied a routine accommodation that other employees with similar limitations received.
- You were pushed onto unpaid leave when you asked only for a minor adjustment.
Can I be fired for calling in sick while pregnant?
This is one of the most common and most stressful situations. The honest answer: it depends on why you are being disciplined and whether your absences are protected.
- If your absences are for a pregnancy-related condition (severe morning sickness, complications, doctor-ordered rest, prenatal appointments) and you are covered by the FMLA, that time may be protected leave. You cannot lawfully be fired for using leave you are entitled to, and FMLA-protected absences generally cannot be counted against you under a no-fault attendance policy.
- If you are covered by the PWFA or ADA, time off or schedule changes for a pregnancy-related condition can be a required reasonable accommodation, even if you are not FMLA-eligible.
- If you are not covered by any of these (for example, a very small employer with no applicable state law) and your employer applies a neutral attendance policy the same way to everyone, then absences may not be protected. The key test is consistency: an employer cannot punish a pregnant worker for sick days while excusing the same absences from others.
The practical move is to connect your absences to your pregnancy in writing and, where possible, get a brief note from your medical provider. That converts what looks like "calling in sick" into a documented, potentially protected medical absence and forces the employer to engage with the leave and accommodation laws rather than just an attendance policy.
