I disagree; I and a few other good coworkers were managed by a pretty horrible boss (pretty horrible as in he is known by name as a horrible person to work for by multiple corporate HR departments and recruiting agencies in our metropolitan area who all wanted to poach us), and I think we all gave our two weeks notices when we could. You should always act in a way that optimizes your own desirability as an employee or a person to be associated with in order to keep your options open. It's very rare to find yourself on a hill worth dying on, and to have that hill be clearly seen by others. For me, that standard is not letting an employee go to a funeral, or be at the birth of your child, or something timeboxed and will cause similar extreme emotional/mental pain and duress. Of course, the flip side is to not have your internal judgments skewed by constant interactions with said boss or bosses. I'm guessing that's how you become a bad boss or employee over time.
