Massachusetts At-Will Employment Laws: Exceptions and Your Rights

Massachusetts is an at-will employment state, meaning an employer can terminate an employee at any time, for any reason or no reason at all, and an employee can likewise quit at any time. The at-will default is long established under Massachusetts common law, though the Supreme Judicial Court has recognized three significant exceptions that limit an employer's power to fire.

Is Massachusetts an at-will employment state?

Yes. Massachusetts follows the at-will employment doctrine under common law. An employer does not need to give a reason, provide notice, or show cause before ending the employment relationship. Similarly, employees may resign at will without legal liability. This default rule has governed Massachusetts employment relationships for well over a century, and it remains the baseline unless one of the three recognized exceptions applies or the parties have contracted for something different.

Exceptions to at-will employment in Massachusetts

Massachusetts recognizes all three major common-law exceptions to at-will employment, though the good-faith covenant operates more narrowly here than in most states that recognize it.

Public-policy exception (recognized). The Supreme Judicial Court established this exception across two decisions. Smith-Pfeffer v. Superintendent of the Walter E. Fernald State School, 404 Mass. 145 (1989), confirmed that an employer may not discharge an employee for: (1) asserting a legally guaranteed right, (2) doing what the law requires, or (3) refusing to do what the law forbids. Flesner v. Technical Communications Corp., 410 Mass. 805 (1991), added a fourth category: (4) performing important public deeds that the law encourages even if it does not absolutely require them. This exception protects workers who, for example, file a workers' compensation claim, report a safety violation, cooperate with a government investigation, or refuse to commit fraud on a customer. The fired employee must identify a well-established public policy rooted in a constitutional provision, statute, or regulation.

Implied-contract exception (recognized). Massachusetts courts have held that language in an employee handbook, written policy, or oral assurances can create implied contractual terms if the language is sufficiently definite. An employee handbook that promises progressive discipline or "termination only for cause" may give rise to an implied-contract claim. However, a clear and prominent disclaimer stating that the handbook is not a contract and employment remains at-will will generally defeat such a claim. Employers who want to preserve at-will status must include an unambiguous disclaimer in their handbooks and offer-letter language.

Covenant of good faith and fair dealing (recognized, narrow). Massachusetts recognized this covenant in Fortune v. National Cash Register Co., 373 Mass. 96 (1977), where the court found that an employer breached the covenant by terminating a long-term salesperson the day before a large commission vested, solely to avoid paying that commission. The court held that a discharge timed to deny a clearly earned or nearly earned benefit is actionable. However, the Supreme Judicial Court pulled back significantly in Gram v. Liberty Mutual Insurance Co., 384 Mass. 659 (1981), clarifying that the covenant does not broadly prohibit bad-faith or unfair terminations. In Massachusetts, the covenant is cabined to situations where the employer fires someone specifically to deprive them of compensation they have already earned or are on the cusp of earning. It is NOT a general "just cause" requirement, and it does not apply to ordinary at-will terminations that happen to be harsh or arbitrary.

Is Massachusetts a right-to-work state?

No. Massachusetts does not have a right-to-work statute. Under federal labor law (the National Labor Relations Act), states may enact right-to-work laws that prohibit mandatory union membership or fees as a condition of employment. Massachusetts has not done so, which means union-security agreements, requiring employees to join a union or pay agency fees as a condition of continued employment in a unionized workplace, are permitted here.

It is important not to confuse right-to-work with at-will employment. Right-to-work laws address whether workers can be compelled to support a union financially; at-will employment is about whether an employer needs a reason to fire someone. The two concepts are legally and practically distinct. As of 2026, 26 states have right-to-work laws, after Michigan repealed its statute effective February 13, 2024. Massachusetts is not among them.

What at-will employment does not allow in Massachusetts

Even in an at-will state, certain terminations are illegal. The federal floor applies across all 50 states: an employer may not fire an employee because of a protected characteristic covered by Title VII of the Civil Rights Act (race, color, religion, sex, national origin), the Americans with Disabilities Act, the Age Discrimination in Employment Act, the Genetic Information Nondiscrimination Act, the Pregnant Workers Fairness Act, or the Equal Pay Act.

Retaliation is also prohibited. Federal statutes forbid firing an employee for reporting workplace safety violations (OSHA), taking qualifying family or medical leave (FMLA), engaging in concerted activity with co-workers (NLRA), blowing the whistle on financial fraud (Sarbanes-Oxley, Dodd-Frank), exercising wage-and-hour rights (FLSA), or seeking veterans' reemployment rights (USERRA).

Massachusetts adds its own layer through M.G.L. c. 151B, the Massachusetts Fair Employment Practices Act, which prohibits discrimination based on race, color, religious creed, national origin, sex, gender identity, sexual orientation, disability, ancestry, age (40+), and several other characteristics. The Massachusetts Wage Act (M.G.L. c. 149, ss. 148-150) provides additional protections for wage claims. Terminating an employee in retaliation for asserting rights under these statutes violates both the public-policy exception and specific statutory anti-retaliation provisions.

If you were fired in Massachusetts

If you were terminated in Massachusetts, it is natural to wonder whether the discharge was lawful. At-will employment means your employer did not have to give you a reason, and a reason they give may simply be false or pretextual. But the absence of a stated reason, or even an obviously unfair one, does not by itself make a firing illegal.

Start by documenting everything: the date of termination, what was said, any written communication, whether the termination came shortly after you filed a workers' comp claim, complained about discrimination, or earned a large commission. Timing and context matter. Consider whether the facts fit one of Massachusetts's three exceptions or whether your situation implicates the federal floor or c. 151B.

Deadlines are strict. Discrimination claims under c. 151B must be filed with the Massachusetts Commission Against Discrimination (MCAD) within 300 days of the discriminatory act. Federal EEOC charge deadlines are also 300 days in Massachusetts. Filing deadlines for wage claims and other matters differ. Consulting an employment attorney as soon as possible after termination is the most reliable way to preserve your options.
