Another good book is The 48 laws of power by Robert Greene that goes beyond Niccolò Machiavelli with many historical examples.
"Everything must appear civilized, decent, democratic and fair .. place your iron hand inside a velvet glove, you cannot opt out of the game. There are no nonplayers. #1 master your emotions.
SidKemp said it right. Sometimes it's better to leave than have an ulcer or TMJ from grinding your teethe. Your health is affected by toxic bosses that will give you an illnesses from stress.
