I think some of them just lack people skills. I had this one manager that nobody liked and was rather prickly, but she very quickly kicked out an asshole customer and then immediately checked to make sure I was okay after. She cared, and actually did more for us than most of the rest of management, but her people skills were terrible.
The number of bosses I’ve had that were massive assholes, but had the mentality of “only I get to abuse these employees” is amusingly high.
