When you join a consulting firm you may be asked to sign pre-employment documents. You'll receive the standard forms, such as W-4, I-9, etc.
But one of the documents with which you'll be presented you’ll not have seen before if you’ve worked only for hospitals: a “non-compete” document.
Some people just say to themselves, “I’ll just sign it, because I don’t want to deal with it, and I’ve heard they’re unenforceable anyway.” Here’s the issue: If there’s a clause in a signed contract that’s unenforceable, you may win if you’re brought to court. But you’re going to have deal with the fact that you’re going against something you agreed to. The best thing to do is to deal with this before you join the firm, so that if and when you decide to leave, your transition will be as smooth as possible.
