A new law that fills a real gap

For years, a pregnant worker who needed a small adjustment — a stool to sit on, a water bottle at the station, a few extra bathroom breaks, a temporary lift restriction — often had no clear legal right to it. The Americans with Disabilities Act (ADA) covered pregnancy-related disabilities but not a normal, healthy pregnancy. The Pregnancy Discrimination Act barred discrimination but did not, by itself, require accommodation. The result was a gap that pushed many workers to keep working in unsafe conditions or leave a job they wanted to keep.

The Pregnant Workers Fairness Act (PWFA) closes that gap. It requires covered employers to provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions, unless doing so would impose an undue hardship. It borrows the ADA's machinery — reasonable accommodation, interactive process, undue hardship — but applies it to a population the ADA often missed. If you have 15 or more employees, the duty is yours, and it is not optional.

What the PWFA reaches that the ADA does not

The single most important thing to understand is that the PWFA's trigger is far broader than the ADA's. Under the ADA, an employee generally must have a condition that substantially limits a major life activity. Under the PWFA, the covered "limitation" can be modest and temporary — it does not need to rise to a disability at all. A routine pregnancy with ordinary discomfort qualifies. The related conditions the law reaches are expansive and explicitly include things like lactation, miscarriage, postpartum recovery, and the need to attend prenatal appointments.

That breadth changes the manager's instinct. The right reflex is no longer "is this a disability?" It is "does this worker have a known limitation connected to pregnancy or childbirth, and can I adjust something to help?" A job description built around an essential-functions analysis is still useful, but the PWFA leans harder toward finding a way to keep the worker working than the ADA does — the whole point of the law was to stop pushing pregnant workers out.

What "reasonable accommodation" usually looks like

PWFA accommodations are mostly small, cheap, and temporary. The regulations and legislative history repeatedly cite a set of adjustments that are so common they are essentially expected:

  • Sitting or standing as needed (a stool, permission to alternate).
  • More frequent or longer breaks — for the bathroom, to eat, to drink water, to rest.
  • Water at the workstation.
  • Temporary reassignment of strenuous or hazardous duties, or a temporary transfer to lighter work.
  • A flexible or adjusted schedule, including time off for prenatal or postpartum appointments.
  • A modified uniform or safety gear that fits.
  • Telework where the job allows it.
  • Leave to recover from childbirth or a related condition — but leave is a last resort, not a default. Forcing an employee onto unpaid leave when a simpler on-the-job adjustment would work is one of the law's named violations.

Notably, the regulations recognize a handful of "predictable assessments" — accommodations so minor and so obviously reasonable (carrying water, extra restroom breaks, sitting/standing, taking breaks to eat and drink) that denying them will almost never survive an undue-hardship defense. Treat those as effectively automatic.

The interactive process — and the trap of asking for too much

Like the ADA, the PWFA expects an interactive process: a good-faith, back-and-forth conversation to identify a workable accommodation once the employee makes the limitation known. The employee does not need magic words or a formal written request — a plain statement that they need an adjustment because of pregnancy is enough to start your obligation.

Here is the sharpest departure from ADA habits, and where employers get into trouble: under the PWFA, you generally may not require supporting medical documentation for many common accommodations. Demanding a doctor's note for a stool, a water bottle, or extra bathroom breaks is itself a violation for the predictable-assessment items, and documentation may only be sought when it is reasonable to do so under the circumstances. If your ADA muscle memory is "always get the paperwork," you must consciously override it here. Over-documenting is not caution — it is a compliance risk.

Two more prohibitions worth memorizing:

  • You cannot deny an employment opportunity (a job, a promotion, training) because someone needs a PWFA accommodation.
  • You cannot force a leave or any other accommodation on the employee if another reasonable accommodation would let them keep working. The employee's ability to stay on the job is the goal.

Undue hardship is a real defense, but a high bar

You are not required to grant an accommodation that imposes an undue hardship — significant difficulty or expense judged against your size, resources, and operations. But because the typical PWFA accommodation is minor and short-lived, the hardship defense rarely succeeds for the common requests. Save it for genuinely disruptive asks and document your analysis if you invoke it. Denying a stool because "it's not how we do things" is not undue hardship; it is a lawsuit.

How the PWFA sits alongside your other obligations

The PWFA does not stand alone. A pregnancy accommodation will often overlap with:

  • The ADA, if a pregnancy complication becomes a covered disability — you may owe duties under both.
  • The FMLA, for eligible employees needing job-protected leave around childbirth. Coordinate the two so an accommodation and protected leave are tracked cleanly rather than colliding.
  • The PUMP Act, which independently requires reasonable break time and a private, non-bathroom space to express breast milk. Lactation is also a PWFA-covered condition, so the two reinforce each other.
  • State laws, many of which impose broader pregnancy-accommodation duties, reach smaller employers than 15, or apply to conditions the federal law does not.

Fold all of this into your written policy. If your employee handbook still treats pregnancy only under an anti-discrimination heading, it is out of date — it needs an affirmative accommodation policy and a named person to route requests to.

A short playbook for managers

  1. Listen for the trigger. Any mention of a pregnancy-related limitation and a need to adjust starts the clock. No form required.
  2. Do not ask for a doctor's note by reflex — especially for the small, predictable accommodations.
  3. Start the interactive conversation promptly and in good faith; look for a way to keep the person working.
  4. Grant the minor, obvious adjustments essentially automatically.
  5. Reserve leave for when nothing else works — never impose it as the easy default.
  6. Document the request, the conversation, and what you provided (or, rarely, why hardship justified denial).
  7. Never retaliate or let the accommodation affect assignments, reviews, or advancement.

The bottom line

The PWFA gives pregnant and postpartum workers something they lacked for decades: a clear right to the small, sensible adjustments that let them keep doing their jobs safely. For an employer with 15 or more people, the duty is broad, the typical accommodation is cheap, and the fastest route to liability is old ADA reflexes — demanding documentation or defaulting people onto leave. Retrain managers to start the conversation, say yes to the small stuff, and keep good records, and compliance becomes what it should be: retaining a valued employee through a temporary season instead of losing them.

This is general guidance on the Pregnant Workers Fairness Act, not legal advice. PWFA regulations, documentation limits, the list of predictable assessments, and overlapping state pregnancy-accommodation laws are detailed and evolving — confirm your specific obligations with an employment attorney before denying any accommodation request.
