Except… this sort of contract is no longer considered to be legal in the United States.

I’m really looking forward to the lawsuits, to be honest.

Edit: lol wow, derp. This is NDA, not non-compete (the article I linked). But that said, companies will often make NDA contracts that are legally questionable, and as was mentioned (and linked to) further down the thread, the NLRB has ruled that NDAs that effectively force employees to broadly surrender their labor law rights are unenforceable.
