When I was in elementary school, we had a woman come in as the principal when the man who was there either quit or was transferred. She was pretty strict and was never very nice to students, I thought. She made everyone walk out and around the school, instead of through it, to get from one side to the other during recess. She never explained it, only said, "It's a beautiful day outside, go out and around." Some students egged her car once because no one really liked her.
As far as bosses go...the worst I ever had was a guy I worked for during the Goodwill Games in St. Petersburg, Russia. He was a former drill sargent, and hardly ever acknowledged anyone for doing a good job, only yelled at people constantly. He was probably the most American of all the Americans who worked in operations at the games, and I don't mean that in a flattering way at all. He thought Russians were stupid, which was to his disadvantage, because he didn't speak a word of Russian, and all of them talked smack about him right in front of him, including me. He was also ignorant of the Russian culture, and didn't care if he offended people.
The worst thing I can remember was that he would scream at me to do my job when I was already doing it. Once, he called me on my cell phone to yell at me that if he didn't have a truck at a certain location at a certain time, he would have me terminated. I had already made arrangements that morning for the trucks, but that wasn't good enough for him. So, knowing that the site my boss would be at was the site that would need the largest truck, I deliberately sent the smallest truck I could find IMMEDIATELY to where he was. By God, if he wanted a truck, I would give him a truck! He couldn't say anything because I had done what he asked, even if he didn't get the truck I knew he needed.
At the end of the Games, the guy stiffed me on my bonus, and I never saw him again. All I can say is, what comes around goes around, and I hope he got his!
