New bosses need a lot of help. If they are very young, under age 30, they need to do a little maturing.
They need to remember employees are human, and life happens to everyone. They need to remember the Golden rule or "treat your people good and they'll treat you good." (or take of the employees and the employees take care of the boss.) They need to remember what they went through to get to be a coach, and where they came from, and finally take some HR classes along the way, so they can learn some diplomacy. The government is guilty of hiring very good technical experts, who need lots of help with people skills.
