Incompetence can also be seen on how subordinates deal with their bosses.
Workers feel anxious on how their bosses think about them. Should I correct my boss? Does he think of me as a competitor? Am I capable enough? Should I take an action?
Of course, everyone would think of those question before making a move. But a wise subordinate know can recognize that a boss does not know what he needs and the best thing to do is address their suggestions to the boss. Why? Because the boss is the one with the greater power to act.
