One quick Margaret story, we had an employee group at the airport that the company supported and helped out. They held meetings with speakers coming in and good lectures and interesting stuff.
One time we had an open house with some management, and she attended to try to look like a bigwig. This group was made up of very dedicated folk, good workers and all that. She did some management spiel, and this really nice guy, a mexican national who had his green card and was persuing citizenship, and was going to go to college for aeronautics got up to speak and ask some questions.
He had some criticisms of the ramp and offered some proactive solutions.
She got offended, went back to HQ and pulled his file and tried to terminate him.
She didn't get away with it, I had a tiny bit of oversight over her department (and knew where the skeletons were buried).
Another time she discovered an employee she was over was on anti-depressants, and fired her.
Then bragged to her department about how she "fired her ass." I tried very hard to get her to file with the Dept of Labor, she had an ironclad case, but she was too freaked out by the evil #### Margaret.
Pure distilled evil. For every story I have, I have 20 more.
