I won't generalize, but my observations of a female boss I had within the court system were that she was insecure and hostile toward anyone else who had as much education as she (she had a master's degree; I had a law degree and two fellows had MBAs - she hated, resented and feared us), but fawned over and promoted those with high school diplomas who were unqualified for and incompetent in their new positions. She also was an alcoholic and never closed the stall door when she went to the rest room, but I digress The administrator where I work...is a dead ringer for the person you've described above. Although I've never been in the bathroom with her.....HA!! Never will either.
The absolute crazy part is....she's not been fired yet. It's like working in Bizarro World.
