Have you ever been part of a corporate re-org where you were technically laid off and rehired and thus were legally forced to sign a new agreement? Such freedom!
All "contracts" that fit a pattern of take-it-or-leave-it with a zillion provisions should be negotiated by the government, a union, or some other collective entity with a reasonable claim to protecting the interests of the side that has no leverage alone.
Plenty of agreements are heavily constrained by regulators, (think insurance for example) and we take it for granted, so I am not suggesting any radical idea, just pushing back on the weasels who are always working at corrupting things.
