I was accused of not having enough to do by a boss. He was habitually late to everything. I am at every meeting 3 to 5 minutes early, because I leave every meeting at the :20 or :50 depending. Then I have 5 minutes to pee or whatever before going to the next one. Either way, he saw me get to meetings a few minutes early and legitimately accused me of not having enough to do. That was one of two jobs that I've ever walked out of.
