Massachusetts reasonable‑accommodation requirements

Coverage & definitions

Massachusetts’ anti-discrimination law, M.G.L. c. 151B, § 4, applies to employers with six or more employees — well below the federal ADA’s 15. “Handicap” (the statute’s term) is broadly defined to include physical or mental impairments that substantially limit a major life activity, a record of such an impairment, or being regarded as having one.

Qualified employees and applicants are those who, with or without reasonable accommodation, can perform the essential functions of the job. Since April 1, 2018, the Massachusetts Pregnant Workers Fairness Act has folded pregnancy and related conditions — expressly including lactation and the need to express breast milk — into the same statute with its own accommodation duty.

Reasonable‑accommodation duties

Employers must provide reasonable accommodations to qualified employees or applicants with disabilities unless doing so would cause undue hardship, meaning significant difficulty or expense judged against the employer’s resources and operations. Examples include job restructuring, modified work schedules, physical modifications to the workplace, technology aids, and more flexible policies.

For pregnancy and related conditions, the statute lists accommodations including:

• More frequent or longer paid or unpaid breaks.
• Time off to attend to a pregnancy complication or recover from childbirth.
• Acquisition or modification of equipment or seating.
• Temporary transfer to a less strenuous or hazardous position.
• Job restructuring.
• Light duty.
• A private non-bathroom space for expressing breast milk.
• Assistance with manual labor.
• A modified work schedule.

Three prohibitions apply: an employer may not take adverse action against an employee for requesting or using an accommodation, may not require an employee to accept an accommodation that is unnecessary or that the employee declines, and may not force an employee onto leave if a reasonable accommodation can be provided instead.

Notice, documentation & the interactive process

Massachusetts imposes an affirmative written notice duty. Employers must give employees written notice of the right to be free from pregnancy-related discrimination, including the right to reasonable accommodation, at three points:

• To all employees generally, in a handbook, pamphlet or other means.
• To new employees at or before the start of employment.
• To any employee within 10 days of that employee notifying the employer of a pregnancy or a related condition.

The notice can be delivered electronically or on paper, but it must cover both the anti-discrimination right and the accommodation right.

The statute also draws firm lines around documentation. An employer may require that documentation supporting a pregnancy-related accommodation come from an appropriate health care or rehabilitation professional — except that no documentation may be demanded for four accommodations: more frequent restroom, food or water breaks; seating; limits on lifting more than 20 pounds; and a private non-bathroom space for expressing breast milk.

Documentation may be required for an extension beyond the originally agreed accommodation. For disability accommodations generally, employers may ask for limited documentation confirming the need, and must keep it confidential.

A timely, good-faith interactive process is expressly required once the employer is on notice of a need for accommodation. There is no fixed statutory deadline, but the Massachusetts Commission Against Discrimination treats unexplained delay, failure to respond, or refusal to engage as evidence of a violation.

Enforcement & penalties

Complaints are filed with the Massachusetts Commission Against Discrimination (MCAD) within 300 days of the alleged act. The MCAD investigates and can order remedies including job reinstatement, back pay, policy changes, and damages for emotional distress; civil penalties may apply for serious or repeated violations, and a court action is available after the administrative stage.

Failing to provide the required written notice is a violation on its own, whether or not any accommodation was later denied.

Practical tips for employers

• Put the pregnancy-rights notice in your handbook and your onboarding packet, and diarize the 10-day notice from the moment an employee tells you they are pregnant.
• Build the four no-documentation accommodations into your intake form so no one asks for a doctor’s note for a chair or a water break.
• Treat a request for an extension differently — documentation can be required there.
• Train managers to recognize requests even when the employee does not use legal terms.
• Document each step of the interactive process and keep medical information confidential.
• Never assume undue hardship without exploring alternatives; the six-employee threshold means small employers are fully covered.
