There was a story where an employee was fired by mistake. It was an automatic procedure and he had all his access revoked, computer and physical.
No one could un-fire him, the only solution was to hire him again as if he was a new employee.

Edit: I guess a fair number of states do have laws for that, though unlimited vacation still gets around that.
