A guy I've known for many years recently got a small promotion, one in which he will be supervising other people. (The back story is that he's been telling his current employer he's got "twenty years management experience", which is, IMHO, such a wild exaggeration as to qualify as an outright lie.) The problem is that he is an absolutely terrible manager. He panics under the slightest pressure; is terribly impatient; is dreadfully disorganized; has a total lack of empathy; is bad tempered; boasts constantly; and more than a little insecure. And thats me speaking as his friend. Several of the people he oversees have come to me for advice. Which puts me in something of a dilemma. On the one hand, I don't want to see my acquaintance fail in his new job. On the other, I don't want the people working with him to endure months (if not years) of his micromanaging nonsense. I've pondered long and hard as to the best way to handle the situation. I can't really go to upper management and tell them they've made an awful choice (they didn't consult me before making the promotion.) So far the best idea I've come up with is to give this guy a small business book on effective people-management (Zapp! The Lightning of Empowerment) that I got very early in my business career. The concerns I have are that a) this guy will say he's "too busy" to read a 110 page book; b) that he will feel that I am not-so-subtly criticizing his management style; and c) is unlikely to change his ways under any circumstances. Any other ideas as to how to approach this situation?
