Recently, a friend of mine switched jobs and started a new position where the leader valued him highly, appointing him as the supervisor in charge of a department. But a problem arose: one of the employees under him was not "obedient" and had poor performance. My friend asked me how he should handle this situation - should he fire the employee or not?
