England - line manager unfair appraisal
Hi. England, employed 2yr 1 mth. I've had lots of positive feedback from my team and clients, things haven't been perfect but been ok. I was very loosely managed until now by a series of different managers and had no written job description.
Recently ie late April-
A new Line Manager (head of dept who joined after me) has taken me on. We have worked together on projects with some friction involved, as we are both very experienced people with different views of what good looks like
Company has issued a new 5 point impact rating as part of the appraisal process
Line manager has provided me a written job description
LM has written up an overall favourable review based on gathered feedback. It identifies some areas of improvement. The issue I have is she has also given me a low impact rating which pretty much spells out under performance. The impact rating language seems totally at odds with what is written in her review. She says I am not meeting the job description which apparently is her reason for scoring me so low.
I have emailed her and HR spelling out exactly how the impact rating description doesn't match the managers review/feedback and asked for it to be realigned correctly to a higher score.
I suspect I will receive a double down response by email saying the score cannot be undone.
What process can/ should I otherwise take? I can't stand for this. It's totally unfair.
Thank you.
