I was sexually harassed by a co-worker and then blamed by HR for his doing it, because I was talkative and friendly and one of my skirts was short. They told both of us to say nothing to co-workers, so I never did, while he did and tried to smear my reputation, and of course he got away with it.
I've had so many shit bosses that all of the employees complained about, and they just kept being allowed to do the same shit. There was one manager who was awful, a true sociopath. The company wouldn't do anything. Then suddenly he was out of the office way too much, so a co-worker followed him when he was supposed to be doing something off site for the company and caught him working another job as a manager for another company at the same time! She walked in on a meeting and he got fired there. He wasn't fired immediately with our company, he was given a certain number of days to quit, and on the morning of the last day, when there was only one other person in the office, he faked a stroke. He'd had one in the past. I don't know how he managed to get away with it with the doctors (he was really smart and also had a brother who was a doctor), but the company had to pay for his temporary disability. Then they actually let him come back when he'd sufficiently recovered, but he'd supposedly had memory loss. He said that it had been his habit since he's had memory loss with his first stroke to keep a detailed daily journal, so he knew things about each of us at work even though he didn't remember any of us. Way too many details for a journal. It was so creepy. (And some people on the forum think I'm paranoid when I recognize and call out manipulative bullshit!
This was but one example of the over the top manipulation I've witnessed in my life.)
