In order to handle an unfair boss, it is important to remember to not become reactive to any unfair criticism. Snapping back at an unfair boss only makes the situation escalate even more.
Instead, make sure you document and keep precise records of your work performance. So when the time comes that you may have to prove your boss wrong you have evidence to back it up. In addition, try to get your boss to utilize objective measures to rate your job performance. It is much harder for a boss to rate you unfairly with objective standards set in place. Finally, if you do decide to go above your boss’s head try not to slander them in any way because ultimately that just makes you look bad in the end.
