Plays favorites - you have to be a pushover to get in their good graces
All take, no give attitude - will push you to your absolute limits with no reciprocity
Not open to innovation - isn't interested in new ideas/methods
Ostracizes employees, writes them off at the first sign of dissent (for example, declining a promotion, and getting hours cut and mistreatment as a result)
Poor training, lack of oversight for management
Inconsistent scheduling - you may be sent home early, you may be forced to stay late, you will never get off as scheduled
