4 Steps to Take After a Tough Performance Review

A Fairygodboss member recently shared that she had a bad performance review and was wondering how to proceed.
"I just had a terrible annual review that I thought was very unfair," she said.
"I was really surprised but it was so bad that I think I'm living in an alternative universe to my manager.
Should I just start looking for another job?
The feedback was really different than what I think I deserve so I normally would just try to improve but it feels kinda hopeless."
