I quit my job because my lying, psychotic boss was going thru the process to fire me.
So I told my newly assigned government contact that we needed to get on the ball and get him up to speed as I would be fired in the next 60 days. I refused to discuss any more about my problem until we covered what he (and the government) needed to know about my project.
Then I told him the government contact the problem. His boss made a point of letting me know that the government wasn't trying to get me fired. I told them about the lies and was willing to go thru the computer source code control to prove the lies. They didn't bother, they believed me.
(Government contracts are a bit funny, there are rules for what they can and cannot do regarding a company's choice of its employees to fulfil a contract. They didn't have a whole lot of options to work with in the time I would have left.)
Then I went to my psycho boss's boss's boss. He didn't really know my boss, his office was miles away and he was only on our site a few hours a year. I told him what was going on and that I had been around long enough to know that I was going to be fired no matter what I did at this point. That ship had sailed.
I just wanted him to know that psycho boss had fixated on others until they quit or were fired, and he was bound to do it again. I wanted the company to know that because they were in danger of losing even more good people, and that the company, the client, and my colleagues deserved better than that.
He offered to find me a job at another location.
Before he did, I found another job with a different company at the same location, just down the hall. Better pay, better hours, better technology to work with, and twice the number of holidays. I now get a 3 to 4 day weekend every month without having to take vacation time. :) I got to wave to him in the hall. :)
About 8 months later they escorted psycho ex-boss off the premises. My prior colleagues made sure I knew that.
Good times. I hope he learned from it, but psycho people rarely do.
