I was recently appointed as a mid-level manager at a fairly large company and one of the first tasks handed to me was the appraisals. I am feeling slightly uncomfortable doing them as I have been highly critical of their value in the past. To make matters worse, I will be reviewing the performances of my former colleagues. I do not want to be too critical of them, but I accept that I have to be more managerial now. Is there any way to do this without damaging relationships?
