30 yr exp Hairdresser Non Compete in MA Legal?

Non-competes in Mass. are enforceble to the extent reasonable. If only a 15 mile radius, the non-compete seems reasonable for a limited amount of time (a year or two). If if enforceble, the former employer may choose not to enforce it.

The general principle is that noncompetes are enforceable where the time and geographic restrictions are reasonable. Thirty years sounds per se unreasonable to me, but fifteen miles does not.

That's just the general principle, and not legal advice, as I don't hold Massachusetts licensure. Get thee to a law library and check American Law Reports ("ALR") on the subject of non-competition agreements and their enforceability. I'm sure there's an annotation on the subject collecting the cases, including those in Massachusetts. A law librarian can help you find the ALR index and then look up "non-competition agreements" to find the article.

Good luck. If you need legal advice, please consult a lawyer who holds Massachusetts licensure.
