Years ago, I had a boss at work that was utterly incompetent and he was replaced by somebody new. He decided to stay on in a lesser position so that he could "guide" the new boss and be available for consultation. He thought for sure that after a few weeks of the new boss, everybody would be clamoring for his return.
Well he was immediately frozen out and the department was completely overhauled for the better. After a couple months, the old boss just stopped showing up for work. We never saw or heard from him again until it was revealed that he was working as a night shift manager for some fast food joint.
Be gone like a fart in high upward winds.
