IANAL, but "signing away" isn't really correct terminology here
Of course you should not sign a contract that contains clauses you don't agree with, whether or not it's conventional wisdom or law. My point is only that you really need to be aware of labor law around your work when you go to work for somebody else. The "lost right" that's shown here was actually never a right you had in the first place, at least in most places in the U.S.
