What is the one thing at work you hate more than anything?

IN general.... managers that have been promoted FAR beyond their capability and the cascade effect when those managers promote idiots like themselves.
I have worked for some damn fine managers/directors, guys that REALLY knew what they were talking about and had a grip on reality and overall strategic direction and who were able to communicate that direction IN ANY direction to get the job done. WHich is why LAMERS flatbackers and kneelers make me puke!!!
