One of the more common managerial flaws is trying to do it all. Or, like a helicopter parent for employees, trying to see it all and control all aspects. So, in effect, when a boss won’t delegate, it’s about trust.
Although they might reject the label of “control freak,” these bosses don’t really trust anyone but themselves. Even if your boss is the most brilliant person who ever lived, not delegating is a managerial formula for failure.
