My supervisor just informed me that I have been making a LOT of mistakes lately. This morning I made a mistake when I ran a report. After I had realized the mistake, I immediately went back and fixed it. My supervisor was still mad. A few days ago I made another mistake. My supervisor gave me a huge data entry job that I had to do by myself. I had literally about 400 kids to excuse from certain classes because they were testing in different classrooms. I made ONE mistake by excusing a student for the wrong date. My supervisor was not at all understanding. She asked me what am I going to do to not screw up so much. I really can't answer that. I try my hardest to be super careful. As far as the data entry job goes, I had 400 kids to go and excuse, it took me several hours, and I think one honest mistake out of that many kids was just understandable human error. I apologized to her for the mistake, but she still told me she doesn't know how I could do such a thing. I might like to add, I have caught her in several mistakes, and I never mentioned them to her. I went back and fixed them for her, but remained silent because I feel it would be inappropriate to admonish someone who is higher up than me. I have been coming to work sicker than a dog for the last week, with almost NO voice, my chest hurting every time I talk, I am severely sleep deprived, but I have still been making all those phone calls. I am overwhelmed. Not only do I make calls, but I also take a lot of incoming calls, and I am in charge of all the data entry work. I am being overworked, in my opinion, and I feel like a couple honest mistakes shouldn't be a huge deal. Now I am afraid I am going to lose my job. I honestly hate, detest, loathe, and abhor this job, but I desperately need it until I find something better. I really want to break down right now. I feel so stupid, worthless, and incompetent. I am at a loss.
