My best bosses gave me the privilege of working with them.
The worst bosses never let you forget that you work for them.
There is a vast difference and the worst bosses never get it, it creates the scenario where you do a certain function one hundred times and they say nothing, but make one mistake and they never let you forget it.

The best bosses are always saying things like 'Great job,' or 'Well done,' when you make a mistake they help you fix it and ask 'What did you learn from that mistake?'
