-A manager who makes you feel like rubbish 24/7.
-Develop anxiety that you are scared of working ever again.
-Favoritism and cliques. There are cliques who will favor each other no matter what.
-Some managers can control the whole company and decide who gets fired, even if they are not the manager of the target person.
-No respect for your work-life balance.
-Even if you complain about bullying and harassment, no one listens because all senior managers are friends and they have all conspired to make every employees life a living hell.
