Company/employee relations are well-modeled by marriage between a mortal human and an immortal sociopath. The Ancient Greeks had a fairly extensive literature on such relationships, which tended not to end well for the human, even when the human is exceptional. The gods... err... corporations can always behave irrationally, so even "irreplaceable" people can get dumped.
