The federal law that requires reasonable accommodations for employees affected by pregnancy, childbirth, or related medical conditions is the Pregnant Workers Fairness Act (PWFA), which took effect June 27, 2023. It covers employers with 15 or more employees and requires reasonable accommodations unless the employer can show undue hardship. The PWFA is not a replacement for older protections. The Pregnancy Discrimination Act of 1978 and the Family and Medical Leave Act of 1993 still apply alongside it, and knowing which statute covers which situation determines what an employee can actually ask for.

The PWFA Is the Newest Statute and It Changes the Request Process Entirely

The PWFA became law on December 29, 2022, as part of the Consolidated Appropriations Act, and its enforcement began on June 27, 2023. The Equal Employment Opportunity Commission (EEOC) issued its final regulation implementing the statute, published in the Federal Register on April 19, 2024, with an effective date of June 18, 2024. That regulation is the document that answers most practical questions about what counts as a related medical condition and what an employer must do when asked.

The statute's core command is that a qualified employee with a known limitation related to pregnancy, childbirth, or a related medical condition must receive a reasonable accommodation absent undue hardship. A "known limitation" means the employee has communicated the limitation to the employer, and the communication does not need to use any magic words. Telling a supervisor "my doctor says I can't lift more than 20 pounds until the baby is born" satisfies the notice requirement under the EEOC's regulation.

Coverage extends to employers with 15 or more employees, which mirrors Title VII's threshold. Congress, federal agencies, employment agencies, and labor organizations fall within scope. Small businesses below 15 employees are outside the PWFA but may still be bound by state pregnancy accommodation laws, which in some states apply at three or four employees.

The most consequential structural feature is that the PWFA does not require the employee to be "disabled" under the Americans with Disabilities Act. A pregnant worker with a temporary lifting restriction who would not qualify as disabled under the ADA can still obtain a lifting accommodation under the PWFA. That broadening of access is the practical reason the statute exists.

The Pregnancy Discrimination Act Covers Treatment, Not Accommodation

The Pregnancy Discrimination Act of 1978 amended Title VII of the Civil Rights Act of 1964 and defines discrimination on the basis of sex to include pregnancy, childbirth, and related medical conditions. Its operative rule is comparative: an employer must treat a pregnant employee the same as it treats other employees with similar abilities or inabilities. If a company offers light duty to workers injured on the job, the PDA generally requires the same offer to a pregnant worker with comparable restrictions.

The PDA does not stand alone as an accommodation mandate. For decades, the Supreme Court's 1976 decision in General Electric Co. v. Gilbert held that pregnancy discrimination was not sex discrimination under Title VII, and Congress reversed that holding with the PDA. Even after the reversal, courts read the PDA as a parity rule rather than a right to accommodation, which is why advocates pressed for a separate statute for more than a decade.

The 2015 Supreme Court decision in Young v. United Parcel Service clarified how the parity analysis works. The Court held that a pregnant employee can establish disparate treatment by showing the employer accommodated a large number of nonpregnant workers with similar limitations but refused to accommodate her, which gives her a path to challenge a light-duty policy that excludes pregnancy. That ruling remains the leading PDA accommodation case.

In practice, the PDA carries the burden of comparison. A worker has to identify a similarly situated nonpregnant employee who received better treatment or a policy that disadvantages pregnancy on its face. The PWFA removes that comparison step entirely, which is the single most useful difference for a worker assembling a request today.

The Family and Medical Leave Act Protects the Job, Not the Temporary Restriction

The FMLA entitles eligible employees of covered employers to take up to 12 workweeks of unpaid job-protected leave in a 12-month period for specified reasons, including the birth of a child and a serious health condition. Pregnancy itself is not listed as a serious health condition, but pregnancy-related complications, prenatal appointments in some circumstances, and recovery from childbirth can qualify. The statute is administered by the Department of Labor's Wage and Hour Division.

Eligibility requires 12 months of employment with the employer, at least 1,250 hours worked in the preceding 12 months, and employment at a worksite where the employer has 50 or more employees within 75 miles. That 50/75 test is stricter than the PWFA's 15-employee floor and the PDA's 15-employee floor, which means an employee at a 30-person company has PWFA rights before FMLA rights.

The FMLA protects the leave itself and the right to return to the same or an equivalent position. It does not require an employer to alter a job for a worker who stays on the job with a lifting restriction, a need for more frequent breaks, or modified scheduling. Those are PWFA and PDA territory. A worker wanting lighter duty while continuing to work is asking the wrong statute if she frames the request under FMLA alone.

Leave under the FMLA can run concurrently with leave under other statutes and with employer-provided paid leave, and employers must notify employees of leave designation rights within five business days of learning of a qualifying need. That notification clock is one of the few FMLA time rules employees can enforce directly, and it appears in the DOL's FMLA regulations at 29 C.F.R. Part 825.

A Side-by-Side Comparison Shows Where Each Statute Stops

No single statute covers every pregnancy-related workplace need. Mapping the three side by side shows where one ends and another begins, which is the comparison workers need before filing a request.

Dimension PWFA PDA (Title VII) FMLA
Year effective 2023 1979 (amending Title VII) 1993
Employer threshold 15 or more employees 15 or more employees 50 or more employees within 75 miles
Legal theory Reasonable accommodation absent undue hardship Equal treatment compared with nonpregnant workers Job-protected unpaid leave
Employee eligibility Qualified employee with known limitation Any covered employee 12 months of service and 1,250 hours
Typical remedy Accommodation on the job Damages for discriminatory treatment Reinstatement and leave protection
Need for a comparator None Required Not applicable
Maximum leave protected Not a leave statute Not a leave statute 12 workweeks per 12-month period
Enforcing agency EEOC EEOC DOL Wage and Hour Division

The table reveals a gap that catches people. An employee at an 18-person firm who needs eight weeks off for childbirth recovery has PWFA and PDA coverage but no FMLA coverage, because the firm fails the 50-employee test. Her leave protection then depends on the PWFA's accommodation framework or on a state family leave statute.

Conversely, a worker at a 200-person employer who needs a temporary transfer away from a night shift while pregnant has all three statutes in play, but the request should be framed as a PWFA accommodation because the FMLA does not modify shifts and the PDA requires a comparison she may not be able to make.

The EEOC's 2024 regulation defines pregnancy, childbirth, and related medical conditions in a way that reaches well past the due date. Related medical conditions include termination of pregnancy, including miscarriage and abortion, and recovery from those events. They also include lactation and the need to pump breast milk, which the Providing Urgent Maternal Protections for Nursing Mothers Act (PUMP Act) separately addresses through break time and private space requirements.

Physical conditions listed in the regulation include anemia, sciatica, carpal tunnel syndrome, hypertension, gestational diabetes, and pelvic girdle pain. Mental health conditions include anxiety, depression, and postpartum depression. The regulation also covers needs arising from fertility treatment and from the use of contraception, which surprised some employers when the final rule appeared in April 2024.

Episodic conditions count. A worker with migraine episodes triggered by hormonal changes can request a modified schedule or a dark workspace during flares, and the limitation does not need to be constant or predictable. The regulation requires the employer to assess the limitation as communicated, not to demand a diagnosis or a prognosis.

Infertility treatment deserves special attention because it produces predictable scheduling needs. A worker undergoing in vitro fertilization may need morning appointments several times in a two-week window, and that pattern fits the PWFA's accommodation framework more cleanly than any other federal statute. The employer cannot demand details of the medical procedure itself, only information sufficient to understand the limitation and the accommodation needed.

The Interactive Process Has Four Predictable Stages and One Hard Limit

A PWFA request follows a structure the EEOC regulation spells out. The employer cannot short-circuit it by demanding documentation at the first conversation or by denying the request before discussing alternatives.

1: The employee communicates the limitation and the needed accommodation, in plain language, to any supervisor or HR contact. 2: The employer and employee engage in an interactive process to identify a reasonable accommodation, and the employer may request supporting documentation limited to the limitation and the need. 3: The employer provides the accommodation, or, if a requested accommodation causes undue hardship, offers an alternative that addresses the limitation. 4: If no accommodation can be provided without undue hardship, the employer may require the employee to take leave, but only if leave is the only reasonable accommodation available and the employee is willing or the leave is otherwise required by law.

The hard limit sits at the fourth stage. Under the PWFA, an employer cannot force a pregnant employee onto leave when another reasonable accommodation would let her keep working, and the EEOC regulation treats forced leave as a violation even if the leave is paid. That rule is the sharpest break from older practice, when employers routinely sent pregnant workers home rather than modify a job.

Failure handling matters. If an employer refuses to discuss the request, demands medical records beyond the limitation, or denies an accommodation without engaging, the employee can file a charge with the EEOC. The charge must generally be filed within 300 days of the discriminatory act in states with a worksharing agreement with the EEOC, or 180 days otherwise, and the deadline runs from the date of the denial.

Four Accommodations That Appear Constantly in EEOC Guidance

The EEOC's final regulation and its accompanying guidance identify several accommodations as presumptively reasonable, meaning an employer should grant them absent a specific, documented hardship. The list is not exhaustive, but it is where most requests land.

Seating or standing options. A stool at a cash register or a standing desk for a worker who cannot sit for long periods. The regulation treats a temporary stool as reasonable in nearly every retail and warehouse setting. Closer parking. A space near the entrance for a worker with pelvic pain or fatigue. The employer does not have to build new parking, only reassign an existing space. Lifting restrictions. A 20-pound or 25-pound cap on lifting, with reassignment of heavy tasks to coworkers. The employer does not have to create a new position, but it must redistribute tasks that fall within existing job functions. Break time and schedule flexibility. Additional restroom breaks, water breaks, and shifted start times for morning appointments. The PUMP Act separately requires break time to express breast milk for up to one year after birth.

Two other accommodations appear often enough to mention. Uniform and safety equipment modifications, such as a larger vest or a different respirator fit, fall within the framework. Telework for a worker with a condition that makes commuting difficult is analyzed case by case, and the EEOC has not treated it as presumptively reasonable.

The reverse side of the presumptive list is worth knowing. An employer can rebut a presumptive accommodation by showing it would impose significant difficulty or expense, but the regulation requires the hardship to be specific to the employer's operations. A blanket policy against light duty does not establish undue hardship on its own.

Undue Hardship Follows the ADA's Definition, Which Sets the Bar High

The PWFA borrows the ADA's definition of undue hardship: an action requiring significant difficulty or expense in light of the employer's size, resources, and the nature of the operation. That standard is stricter than the "de minimis" cost test used in religious accommodation cases, which means employers face a heavier burden defending a denial under the PWFA.

The factors the EEOC weighs include the number of employees, the employer's budget, the number of workers needing the accommodation, the duration and nature of the need, and the impact on the business. A small landscaping company with eight crews may show hardship in reassigning a lift-restricted worker during a peak season, while a national retailer with 300 stores likely cannot make that showing.

The burden of proof sits with the employer. The employer must show hardship, not merely assert it, and the regulation requires the employer to consider alternatives before denying a request. An employer that says "we don't have light duty" without examining whether tasks can be redistributed has not met the burden.

A specific limit applies to the leave-as-last-resort rule. If the employee cannot perform the essential functions of the job even with accommodation and leave would not help, the employer may treat the situation under ordinary ADA and performance rules. The PWFA does not convert every pregnancy-related absence into protected leave.

How the PWFA Interacts With State Law and the ADA

The PWFA sets a federal floor, and state laws can go further. California's Fair Employment and Housing Act requires reasonable accommodation for pregnancy and related conditions with no employer-size threshold for some provisions, and it adds a mandatory transfer right to a less strenuous position. New York's Human Rights Law covers pregnancy accommodation at employers with four or more employees.

The practical consequence is that a worker in a 10-person shop in New York has state accommodation rights, no PWFA rights, and no PDA rights. A worker in the same shop in Texas would have none of the three unless a local ordinance applies. Checking the state statute is the step workers most often skip, and it matters most in small businesses.

The ADA also intersects. A pregnancy-related condition that rises to the level of a disability, such as severe preeclampsia with lasting organ effects or postpartum depression meeting the ADA's definition, triggers ADA accommodation rights in addition to PWFA rights. The ADA adds remedies the PWFA lacks, including compensatory and punitive damages in some cases.

Retaliation protection spans all three statutes. Filing a PWFA charge, requesting an accommodation, or complaining about pregnancy discrimination is protected activity under each of the three laws, and an employer that demotes or discharges a worker after a request faces a separate retaliation claim regardless of whether the underlying accommodation claim succeeds.

The regulatory landscape also shifts with elections and agency priorities, and the EEOC's enforcement posture on the PWFA has varied since 2023. Workers relying on the statute should confirm the current EEOC charge process and any updates to the regulation on the agency's site before filing, because procedural details change more often than the statutory text.
