Massachusetts Employment Contract Review
Reviewing a job offer or employment agreement in Massachusetts? The clauses that matter most, the non-compete, invention assignment, and arbitration, are governed by Massachusetts law, and the same clause can be enforceable in one state and void in the next. Here is how Massachusetts treats each, and what ClauseAudit checks before you sign.
Non-compete in Massachusetts
Generally enforceable if reasonable
Typical enforceable duration: 12 months
Are non-competes enforceable in Massachusetts?
Enforceable under the 2018 Noncompetition Agreement Act, but requires garden-leave pay or other consideration and a 12-month cap. Strict formalities apply.
Governing law: Massachusetts Noncompetition Agreement Act, G.L. c. 149 §24L.
Whatever the label in your contract, Massachusetts courts look at whether the restriction is reasonable in duration, geography, and scope. A nationwide, multi-year, whole-industry ban is far more likely to be narrowed or struck down than a narrow one.
Who owns what you invent in Massachusetts?
Massachusetts does not have a specific personal-invention carve-out statute, so a broad IP-assignment clause can reach more of what you create, potentially including side projects. Read the assignment scope and push to limit it to work actually related to your job.
Arbitration and class-action waivers in Massachusetts
Massachusetts generally follows the federal rule that arbitration agreements are enforceable. Before you sign, check whether the clause is mutual and whether it waives your right to a class or collective action, you are usually giving up the right to sue in court.

Massachusetts employment contract FAQ
Are non-competes enforceable in Massachusetts?
In Massachusetts, a non-compete is generally enforceable if it is reasonable in time, geography, and scope (see Massachusetts Noncompetition Agreement Act, G.L. c. 149 §24L). Enforceable under the 2018 Noncompetition Agreement Act, but requires garden-leave pay or other consideration and a 12-month cap. Strict formalities apply.
Can my Massachusetts employer own inventions I make on my own time?
Massachusetts does not have a specific statute carving out personal-time inventions, so a broad IP-assignment clause can reach more of what you create. Read the assignment scope carefully and ask to limit it to work related to your job.
Do I have to sign a mandatory arbitration agreement in Massachusetts?
Massachusetts generally follows the federal rule that arbitration agreements are enforceable. Check whether the clause is mutual and whether it waives your right to a class action, and know that you are usually giving up the right to sue in court.
Are non-competes enforceable in Massachusetts?
Massachusetts is one of 38 jurisdictions where a non-compete is generally enforceable if it is reasonable in duration, geography and scope. Enforceable under the 2018 Noncompetition Agreement Act, but requires garden-leave pay or other consideration and a 12-month cap. Strict formalities apply. See Mass. Gen. Laws c. 149, § 24L.
How long can a non-compete last in Massachusetts?
Courts in Massachusetts have treated 12 months as the outer edge of what is typically reasonable for an employee. Duration is only one factor: geography and the scope of restricted activity are weighed alongside it, and a term that is reasonable for a senior employee may not be for a junior one.
What if I work in Massachusetts but my employer is in another state?
It matters, because Massachusetts's neighbours do not all treat non-competes the same way: New Hampshire (limited), Rhode Island (limited). Which state's law applies turns on the governing-law and venue clauses in your contract and on where the work is actually performed, so those two clauses are worth reading closely before you sign.
If a Massachusetts non-compete is too broad, does it get narrowed or thrown out?
Courts may rewrite an overbroad restriction to something reasonable. That cuts against you: an employer has little to lose by drafting wide, because a court can pare the clause back rather than discard it. Negotiating the wording before signing matters more here than in states where an overbroad clause simply fails.
Is there anything specific to Massachusetts worth knowing?
Applies only to agreements signed on or after 1 October 2018.
What else should I check in a Massachusetts employment contract?
Beyond the non-compete: how invention assignment is worded and whether it reaches work done on your own time; whether disputes go to arbitration and whether class actions are waived; whether notice periods are symmetrical between you and the employer; and how any equity vests, including what happens if you leave before a cliff.
