@Boxingshibes you should challenge this, I'm fuming on your behalf.
I have had the experience of some total nonsense like this. It was part of a bigger picture - I'm sure some other posters will have heard of this. Basically appraisals etc were set so that nobody could get a top score. I think at one point it was part of an HR trend.
So I went into mine and the only criticism was that I didn't know enough about one of the company's many projects. It wasn't my project. It wasn't linked to my projects. When pressed, they said that when I had been asked a question about details of the project, I had referred the querant onto the relevant team. Which of course I would do, what would be the point in talking to me about it? Or anyone else not working on that particular project?!
When I walked out of that meeting, I was really quite stunned. Then I found out all sorts of shit directives that had come from the top to ensure that nobody got the top score.
Anyway, there were loads of complaints from people about their own appraisals. When I went back in for the follow-up, they found a graceful way to say it was all a load of bollocks. And scores were recalibrated across the whole company.
I also asked them to put it in writing. (This was negated when I found out the bigger picture).
They do have to think more carefully about what they're doing when it's written down.
Being unable to get hold of someone to sign a card is not something that should even be part of any workplace evaluation!
