Leadership, authority, command, etc. have many forms that don't necessarily match up with what is effective or how people would like to be treated as a subordinate. Assuming that managers know better than to be assholes to their employees (or vice-versa) is a huge and very wrong assumption. Social skills also benefit from training and practice like anything else. Many people have never seen or experienced professional and competent management, so they have no example to follow or model to emulate.
