The boss had it in for me. I got along with everyone else at the company, and because I was generally well-regarded and also due to the amount of turnover lately, it would have been alarming to the team if I were just straight fired. So he started setting me up for failure. He started imposing arbitrary requirements and deadlines, became oppositional to everything I said, and went out of his way to point out my shortcomings in public, probably to help sell the team on why he fired me. We used to get along, but something changed along the way, and I suspect at least a part of it was something personal where I might have inadvertently offended him. When I finally realized that he didn't want me to succeed, which meant it was probably impossible to succeed even with my best effort, I submitted my resignation.
