I'm in a US state that allows non-competes. I recently turned down a job because I wasn't comfortable with the non-compete I was compelled to sign expressly because the company's opinion of its own market was so broad. They implored me to trust that they had "never sued anyone" and "have no intentions to", and I think they honestly believe that. But then why have the non-compete at all?
And even if they are true to their word, what happens when they sell the company to someone else that exploits the leverage the non-compete provides?
A friend of mine was sued by their ex-employer over the violation of a non-compete. He lawyered up and fought it. And he won! But it was a Pyrrhic victory that resulted in a significant expensive of time (the judge granted an injunction that forced him out of business until the case was resolved - which was around 18 months) and money (he was granted no financial judgement). I am convinced the plaintiff's lawyer knew they'd lose, but to the suing party the process was punishment and that became their goal.
His should be a cautionary tale - even if you're advised that the non-compete isn't enforceable, it can still hurt you.
