When and how to disclose a pregnancy at work is generally the worker's own call. Federal and state law provide real protections — but the EEOC notes that many of them, especially accommodations, typically kick in once you have asked for what you need. Disclosing early can expose some people to subtle bias; disclosing late can leave others scrambling for accommodations or leave. Most people aim somewhere between week 12 (after the first-trimester risk window) and 28 weeks, depending on the demands of the role and how much accommodation they expect to need. The specifics depend on your situation, and these rules and figures can change.
Startups complicate this. Smaller employers often fall below federal coverage thresholds, so for some workers the protections come entirely from state law. And startup culture rewards "all in" availability — which can make asking for accommodations feel costlier than at a larger company. Many people find that knowing exactly what the law generally guarantees helps neutralize that pressure.
What does federal law say?
How these laws apply depends on your situation, and the rules and figures below can change:
- Pregnancy Discrimination Act (PDA, Title VII): The EEOC explains that employers with 15+ employees generally cannot discriminate against a worker because of pregnancy, childbirth, or related medical conditions, and that affected workers must generally be treated the same as other similarly situated employees.
- Pregnant Workers Fairness Act (PWFA, effective June 2023): Per the EEOC, employers with 15+ employees generally must provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions, unless the accommodation would cause undue hardship. The EEOC describes it as broader than the ADA — covering conditions that are not disabilities.
- PUMP Act (effective 2023): The Department of Labor says most employers generally must provide reasonable time and a private space (not a bathroom) to express milk for up to 1 year after birth.
- FMLA: The DOL describes 12 weeks of unpaid job-protected leave for birth/bonding for workers and employers who qualify (see eligibility on the FMLA page).
- ADA: Pregnancy itself is generally not treated as a disability, but the EEOC notes that pregnancy-related conditions (gestational diabetes, preeclampsia, severe morning sickness) may qualify, which can trigger ADA accommodation duties.
How does this vary by state?
State law varies a great deal here, and these rules continue to change — your state may differ:
California: Pregnancy Disability Leave (PDL) generally provides up to 4 months of disability leave for pregnancy-related conditions, separate from CFRA bonding leave. CFRA also generally adds 12 weeks of bonding leave (so some CA workers can stack PDL + CFRA = up to ~7 months of protected leave). Paid Family Leave (PFL) generally provides partial wage replacement.
New York: Paid Family Leave generally provides 12 weeks paid at 67% of average weekly wages (capped), along with PWFA-equivalent state protections. NYC has additional protections for lactation accommodation.
Massachusetts: Paid Family and Medical Leave (PFML) generally provides up to 26 weeks combined for serious health + family care + bonding, and applies to nearly all employers.
Texas: Generally federal-only. PDA/PWFA/FMLA generally apply if the employer meets the thresholds; there is no state-paid leave program.
How do you handle disclosure, step by step?
1. Many people disclose between weeks 12 and 28
Some people disclose earlier than week 12 — often for roles with health/safety exposure (chemicals, lifting, travel restrictions), or when early-pregnancy symptoms call for an accommodation now. Disclosing later than week 28 can compress the accommodation and leave-planning window — but the timing is your call.
2. Many people disclose in writing where possible
A short email creates a paper trail and, under the PWFA, can help trigger the legal protections cleanly. A script people sometimes use: "I want to let you know I am pregnant. My expected due date is [date]. I will follow up about accommodations and leave planning."
3. Making accommodation requests specifically
Under the PWFA, the EEOC explains that a worker generally needs to request accommodations to trigger the employer's duty to provide them, so it often helps to be specific: "I need to avoid lifting more than 20 lbs," "I need an additional break every 2 hours for nausea management," "I need to work remotely on days I have prenatal appointments." The EEOC describes each request as opening an "interactive process" the employer is generally expected to engage in good faith.
4. Planning leave 60-90 days out
Many people calculate their FMLA / state PFL eligibility early and submit the formal leave request roughly 60-90 days before the expected delivery. A common approach is to stack short-term disability (if the employer offers it) + FMLA + state PFL where applicable. Many employees underuse what is available because no one walks them through stacking — what's available depends on your employer and state.
5. Documenting everything
It often helps to keep copies of: the disclosure email, every accommodation request and response, manager 1:1 notes if performance discussions shift, and leave approvals. Some people save these to a non-work email or personal device, within company policy.
6. Continuing strong work and asking for what you need
Bias often presents as small things: stretch projects routed elsewhere, "team fit" suddenly mentioned, a manager who used to chat now skipping. Many people document those too. They are individually deniable; cumulatively, they can become evidence.
What red flags should you watch for?
- A PIP within weeks of disclosure
- Stretch projects, promotions, or new hires you would normally be considered for suddenly going to others
- Manager language like "are you really committed to coming back?" or "are you sure you can handle this?"
- Accommodations denied without a documented undue-hardship analysis
- A role being "restructured" or "eliminated" during leave
- A "comparable" position offered on return that pays less, has worse hours, or different responsibilities
- Performance feedback that suddenly turns negative right before disclosed leave
- A request to use vacation/PTO instead of designated FMLA/state leave (many people insist on the designation — it generally preserves the reinstatement right)
When should you talk to a lawyer?
Many people consult an employment attorney when:
- They were terminated, demoted, or restructured within months of disclosing pregnancy
- Accommodations were denied without an undue-hardship analysis they find credible
- They returned from leave to a different role, lower pay, or different schedule
- A PIP appeared within weeks of disclosure or shortly after return
- An employer treats pregnancy-related conditions as performance problems
- They are in a state with strong pregnancy protections (CA, NY, MA, IL) and the employer is treating them per the weaker federal baseline
Pregnancy discrimination claims often hinge on temporal evidence — what happened relative to when a worker disclosed. A lawyer's first question is almost always "build me a timeline." Many people start building it early, while events are fresh, regardless of whether they end up consulting.
