Have you ever been cheated out of a promotion?
Yes. I was a grant writer at a museum in Long Beach and my new boss told everyone I was a lousy writer and couldn't do the work. Then she put her own name on whatever I produced. She had no time to work herself because her days were consumed with standing in her doorway and talking with her BFF.
After I left, a colleague put forth some of my work forth at a company meeting without my name on it. Everyone commented on its excellence and jaws hit the floor when she told them who had written it.
The manipulative boss got her fired.
As it turns out, this evil woman hated me because I had been hired by her company rival.
And when they looked further into her background, they found out she had inflated her credentials...made them up, actually...and been fired from almost every job she ever had. She was finally kicked out and no one ever bothered to find out what happened to her.
