I work for a large company and have had my end of year performance review. I marked myself and my other reviewers all marked me as Good Performance (which is the average score). In my mid year review there were no issues and during my regular meetings with my manager there was nothing to cause undue concern. My manager actually gave me more responsibilities and suggested that next year I should seriously think about going in for a promotion, and when I was going to leave a few months ago, they persuaded me to reconsider. However, out of the blue and at my year end review, my manager has marked me as under-performing. I am shocked and I actually feel like crying. It is completely dented my confidence in my abilities as I have never had such a poor performance in my entire career history.
Please can I have some advice how to take it forward from here?? The score will prevent me from taking other roles in the company, affect my pay, and I fear leave me open to redundancy.
