How Long Do You Have to File a Workplace Discrimination Claim in Massachusetts?

In Massachusetts, you generally have 300 days from the date of the discriminatory act to file a charge with a state or federal agency — and missing that window can permanently end your case.

Why Deadlines Are the First Thing That Can Kill Your Claim

Many employees wait too long to act. They hope the situation improves, worry about retaliation, or simply don't know the clock is already ticking. By the time they seek legal help, the filing deadline has passed and their options are gone — no matter how strong the underlying case was.

Acting early is the single most important thing you can do to protect your rights.

The Two Key Agencies — and Their Different Deadlines

Before you can sue your employer in court for workplace discrimination in Massachusetts, you typically must first file a charge (a formal complaint) with one of two agencies:

| Agency | What It Covers | Filing Deadline |

|---|---|---|

| MCAD (MA Commission Against Discrimination) | State law claims under M.G.L. c. 151B | 300 days from the discriminatory act |

| EEOC (Equal Employment Opportunity Commission) | Federal claims (Title VII, ADA, ADEA, etc.) | 300 days in Massachusetts (as a "deferral state") |

Because Massachusetts is a deferral state, the EEOC deadline extends to 300 days rather than the 180-day limit that applies in some other states (as of 2024; verify with counsel).

Filing with the MCAD typically cross-files your charge with the EEOC automatically, which is another reason to contact a Massachusetts employment attorney early.

When Does the Clock Actually Start?

This is where many people get confused. The clock usually starts on the date the discriminatory act occurred — not when you discovered it, not when you reported it internally, and not when HR finished its investigation.

Common triggering events include:

• Being fired, laid off, or forced to resign
• Being passed over for a promotion or pay raise
• Receiving a formal demotion or reduction in hours
• Experiencing a hostile work environment (the date of specific incidents matters)
• Being denied a reasonable accommodation for a disability or religious belief

> Critical warning: For ongoing harassment or a hostile work environment, at least one act of discrimination must fall within the 300-day window. Don't assume that because discrimination started years ago, you've lost your rights — but don't wait to find out.

What Happens After You File?

Filing a charge does not mean you've filed a lawsuit. It starts an administrative process:

1. Investigation — The MCAD or EEOC reviews your complaint and the employer's response.
2. Conciliation or mediation — The agency may attempt to resolve the dispute.
3. Finding or dismissal — The agency issues a finding of probable cause or dismisses the charge.
4. Right to sue — If the process doesn't resolve your claim, you can request a right-to-sue letter and bring a lawsuit in court.

Once you receive a right-to-sue letter from the EEOC, you generally have 90 days to file a lawsuit in federal court (as of 2024; verify with counsel). Missing that deadline after the agency process can also end your case.

Common Mistakes That Cost Employees Their Cases

Knowing what not to do is just as important as knowing the deadlines.

Mistakes to avoid:

• Waiting to see if things improve before filing — the 300 days keeps running regardless
• Relying on an internal HR complaint as a substitute for an agency filing — it is not
• Assuming you need to have already hired a lawyer before filing with the MCAD — you don't, but legal guidance helps
• Not documenting incidents as they happen — dates, witnesses, and written communications are critical evidence
• Resigning without understanding "constructive discharge" — quitting under intolerable conditions may still give you a claim, but timing matters
• Signing a severance agreement without understanding what rights you may be waiving

What to Gather Before You Consult a Lawyer

If you believe you've experienced workplace discrimination in Massachusetts, start collecting the following before your first consultation:

• Dates and descriptions of every discriminatory incident you can recall
• Emails, texts, or written communications that support your account
• Performance reviews showing your work was satisfactory before the discrimination began
• Witness names — colleagues who observed the conduct or heard relevant statements
• HR complaints or company responses (written or email form, if available)
• A copy of your employee handbook or any relevant company policies
• Your pay stubs or offer letters if the discrimination involved compensation

The more organized your records, the faster an attorney can assess whether you have a viable claim.

Massachusetts-Specific Protections Worth Knowing

Massachusetts law (M.G.L. c. 151B) covers employers with 6 or more employees — a lower threshold than federal law, which generally applies to employers with 15 or more employees (Title VII) or 20 or more (ADEA). This means workers at smaller Massachusetts companies may still have state-law protections even when federal law doesn't apply.

Protected characteristics under Massachusetts law include race, color, national origin, sex, gender identity, sexual orientation, age (40+), disability, religion, and several others (as of 2024; verify with counsel for the current full list).
