A new correspondent writes:Most department heads/chairs are fair. That's something I'll just spot for the sake of agreement.Some are not. When it comes to dealing with course approvals and appointments and class schedules, chairs are in a position to reward friends and treat less well those they find objectionable, pains in the ass, or the invisibles. The problem is, especially for the untenured, no one would file a complaint, for obvious reasons. Deans often don't know of the crap that goes on, or if they do, there is blessed little they can do about it.
