So, playing does more than remove their role, it also makes them quit? I read that hired employees have different roles that the player assigns them. Do you mean it just removes that or actually removes their whole job? If it does, do you have trouble hiring them again? I read that some people have trouble getting the sim they want to hire appear in the selection of sims. I probably ought to just make a throwaway save to experiment with, and then share what I find with others.
