What Is a Hostile Work Environment in Massachusetts?

A hostile work environment in Massachusetts is workplace harassment tied to a protected characteristic that is severe or pervasive enough to change the conditions of your job and make the atmosphere intimidating, humiliating, or offensive. Under Massachusetts General Laws Chapter 151B, you have 300 days from the last incident to file with the Massachusetts Commission Against Discrimination (MCAD), and if the harasser is a supervisor, your employer is strictly liable with no good-policy defense available.¹

What Makes Conduct Legally Hostile

Not every bad workplace is a hostile work environment in the legal sense. Massachusetts courts apply a two-part test. The conduct has to be objectively offensive, meaning a reasonable person in your situation would consider it hostile, and it also has to be subjectively offensive, meaning you actually perceived it that way. Both halves have to be met.¹

Courts then look at the totality of the circumstances rather than picking apart each incident on its own. The factors that carry the most weight are:

How frequently the harassment occurred. A pattern of smaller incidents can add up to a hostile environment even when no single event would qualify alone.
How severe each incident was. A single act of physical assault or an explicit threat tied to a protected trait can be enough standing by itself.
Whether the conduct was physical or verbal. Physical harassment is treated more seriously, though persistent verbal abuse can qualify.
Whether the conduct interfered with your ability to do your job.

Isolated offhand remarks or a single rude comment generally will not clear the bar. But harassment is often a steady accumulation of smaller acts, and courts evaluate the pattern as a whole instead of dismissing each piece in isolation.

Protected Classes the Harassment Must Target

Harassment is only unlawful under Chapter 151B when it is connected to your membership in a protected class, whether actual or perceived. General workplace rudeness, favoritism, or personality conflicts do not qualify, no matter how miserable they make the job. The statute covers:²

Race, color, or ancestry
Religious creed
National origin
Sex
Gender identity
Sexual orientation
Genetic information
Pregnancy and related conditions, including lactation and the need to express breast milk
Age (for private-sector and government employees)
Disability (the statute uses the term “handicap”)
Veteran status
Military service obligations

The inclusion of gender identity, sexual orientation, genetic information, and pregnancy-related conditions gives Massachusetts workers protection that goes beyond Title VII of the Civil Rights Act.²

Chapter 151B also reaches harassment based on association. If a coworker targets you because your spouse is of a particular race or your child has a disability, that conduct falls within the statute.¹

Who Did the Harassing Changes Everything

The identity of the harasser determines what you need to prove. This is where Massachusetts law is notably more protective than federal law.

Supervisors: Strict Liability

If a supervisor created the hostile environment, your employer is strictly liable. Once you prove the harassment happened, the company loses. There is no affirmative defense, no opportunity for the employer to argue it had good policies, offered training, or that you failed to report through official channels. The Supreme Judicial Court established this rule in College-Town, Division of Interco, Inc. v. Massachusetts Commission Against Discrimination, holding that the legislature intended employers to be liable for discrimination by anyone on whom they confer authority, with no additional notice requirement.³

That standard is a sharp departure from federal law, where employers facing supervisor-harassment claims under Faragher and Ellerth can defend themselves by showing they exercised reasonable care to prevent harassment and that the employee unreasonably failed to use the complaint process.⁴ That defense does not exist here.

Massachusetts courts also define “supervisor” more broadly than federal law requires. The harasser does not need the power to hire, fire, or demote you. Having some authority over your work, such as the ability to assign tasks or direct your daily activities, can be enough to trigger strict liability.

Coworkers and Non-Employees

If the harasser is a coworker, customer, client, or independent contractor, the standard shifts. The employer is liable if it knew or should have known about the harassment and failed to take prompt corrective action.¹ Reporting the conduct in writing, and keeping a copy, is what puts the employer on notice and starts the clock on its duty to act.

Retaliation Is a Separate Violation

Chapter 151B makes it illegal for any employer, labor organization, or employment agency to punish you for opposing unlawful practices, filing a complaint, testifying, or assisting in any proceeding under the statute. The statute also prohibits anyone from coercing, intimidating, threatening, or interfering with a person exercising rights under Chapter 151B, or with someone who helped another person exercise those rights.⁵

Retaliation can take obvious forms like termination or demotion. It can also look like reassignment to undesirable shifts, exclusion from meetings, or sudden negative reviews that don’t match what you were hearing before you complained. A retaliation claim stands on its own: even if your underlying harassment complaint is ultimately found unsupported, firing or punishing you for raising it is still illegal, as long as you had a good-faith, reasonable belief that the conduct you reported was unlawful.

Filing With the MCAD: The 300-Day Deadline

You must file a complaint with the Massachusetts Commission Against Discrimination within 300 days of the last discriminatory act. Missing this deadline can forfeit your ability to pursue a discrimination claim entirely.⁶

The MCAD investigates the complaint and can facilitate resolution through mediation or conciliation. If those efforts fail, the case can proceed to a public hearing before the commission.⁷

Filing with the MCAD first is generally a prerequisite before you can bring a Chapter 151B claim in state court. If you decide you would rather be in court, Chapter 151B Section 9 lets you move the case:

Within the first 90 days after you file, withdrawing requires written approval from the investigating commissioner.
After 90 days, you can withdraw as a matter of right for any reason, including to file in court, by giving written notice to the commission.

If you also want to pursue a federal claim under Title VII, you can file a charge with the EEOC. Because Massachusetts has its own enforcement agency, the federal filing deadline extends from the standard 180 days to 300 days from the last discriminatory act.

What You Can Recover

Chapter 151B Section 9 provides a strong set of remedies. Courts can award actual damages, which include lost wages, lost benefits, and compensation for emotional distress. Punitive damages are available on top of that when the employer’s conduct warrants additional punishment.⁸

Attorney’s fees are mandatory for prevailing plaintiffs. The statute says the court “shall” award reasonable attorney’s fees and costs, regardless of the amount in controversy, unless special circumstances would make the award unjust. In practice, most successful plaintiffs recover their legal costs in addition to damages.⁸

Age discrimination claims carry an enhanced damages formula. If the court finds the employer committed age discrimination with knowledge that the conduct violated the law, or with reason to know, the court must award between two and three times actual damages.⁸

Courts can also issue injunctive relief ordering the employer to change policies, reinstate you, or take other corrective steps. Temporary injunctions are available even before the MCAD investigation concludes, if you can show irreparable harm in the meantime.
