I had an appraisal recently with deputy line manager. All went well. The appraisal was emailed to me a couple of days later. I printed it off, read it through and signed it. I sent it in internal mail to deputy line manager who signed it and forwarded it on to line manager. A couple of days later I received a copy and noticed that line manager had added another paragraph stating that a topic had been discussed and brought to my attention. This definitely did not happen. I am shocked that it was altered after I had signed it, and that nothing was said to me, I just noticed it when glancing through before taking it home. Can appraisals be amended without notice after the employee has signed it?
