If it ends up being something like 80% non-crucial and stays fired, the other 20% return with double-pay, you’re probably still running a net-positive with better resource allocation
Except in reality the 20% coming back are probably not the best. Some will be but at least some of your best employees are going to be smart enough (or have enough self-respect) to go elsewhere. And/or those are the people skilled enough to find a new job quickly (or know they can find one quickly) and aren’t willing to come back.
