We had one - guy was a manager in my department. Angry all the time, needlessly demanding, micro-manager, backstabbing, condescending - a really class A jerk. He had a particular hatred of women in positions of authority, women in IT, women who aren't thin and beautiful (we'd all overheard his long tirades at his wife by phone about her weight). Our old director was useless, and let him get away with it - his employees HATED him. When old director went on sick leave for a few months, and new director met the twit, he was gone in a few weeks - transferred to management in another department (and, I heard, a 1-for-1 swap for a guy who was the manager in that new department, who is now in an unrelated department and happy as a clam).
New department, old jerk - he's put in charge of managing one of the development groups, specifically on a tool that his old department (my current department) uses daily. Who gets put as his point of contact in our department? Me. (yes, the fat lesbian who refused to put up with his nonsense when we worked together). He flatly refused to deal with me.
His tool is now slated for end-of-life in the next year. Wonder why?
