Same thing happened to my wife. A newly promoted VP transferred her out of a great position she loved to work on a special project he invented to make department look innovative, under promise of a promotion once complete. Instead as soon as the project was done he hired a new manager into another newly created position above my wife, only supervising her. He proceeded to have the manager take all her responsibilities and make her life hell until she quit. Manager was told she would get a director position for doing it, instead they did the same to her a few months later until she quit too. VP promoted to SVP.
