I was a golden-girl director of a department in a southern conservative corporation until, much to my surprise, a man with no qualifications even near mine was promoted over me to run my department. This was a man I had just a year ago helped "get ahead" and even coached on his salary negotiations. When I asked my boss why he was promoted over me I was told because I had "a bad attitude." When I calmly asked for specific examples none could be provided. One was lamely offered up as a reason but was quickly proved to be incorrect.
Alas, the guy moved up over me and I quietly went about my job of being the one actually running the department when I found out that he had be secretly meeting with one of my employees about splitting the department and giving the younger guy half my employees. The younger guy came and told me about this because he was so upset about it going on behind my back. He and I decided to together to talk to our new boss about it. The new boss then wrote us a threatening and nasty email.
I then met with the HR Director after that to ask for his advice and he questioned my integrity and threatened my employment (mind you, I had a stellar record prior to this). I later found out my new boss and this HR Director were buddies and good friends and had also been talking about this behind my back and my fate was pretty much sealed regardless of what I did. They were both soon promoted to VPs. I soon resigned my position and now I make more money working for myself.
