Sorry for the long post.
I am currently having some issues with my boss. After returning from time off over Christmas, I noticed her attitude towards me had changed for the worse. She was extremely critical of my work and pointed out any errors made rather publicly. I'm not sure what happened to cause this change in attitude but it has continued ever since.
It appears to be worse if I have a few days off and upon my return there are always 'problems' with my work, which she sarcastically remarks on. I got very annoyed a few weeks ago, when I returned from being off sick for 3 days and even though I still wasn't 100%, my work was still frequently criticised over the first few days. She was indirectly blaming me for not chasing up a file which was left with a colleague for their action to be done from 5 months ago. She went off on a rant in front of her boss about it with only me in the room at the time. I felt so bad as I couldn't believe I could've done this and with so many other 'mistakes' being made apparent, I lost a lot if confidence in my work.
The next day I got the file back to find that i had not dealt with the file 4 months ago and that my colleague did as I had been off at the time. I brought this to my boss's attention that it was not my fault, but she didn't say very much other than 'oh well'. Nothing was said to my colleague. I didn't want her to continue unnecessarily critisizing my work so The following day I spoke to her privately and asked her not to assume that all mistakes were my fault and that when I was off, I didn't want to be getting the blame for mistakes just because I wasn't there. I also emailed her boss about another work matter, but also mentioned that I had not dealt with the file that caused such an issue to try and defend my work.
Since this she has been trying to trip me up and turn colleagues against me. She has been talking about our conversation to her colleagues even though it was supposed to be private. I don't know what to do. My colleague last week noticed that she was 'harsh' on me (in their words) and so did defend me, which I thanked them for. She has since been 'chatting' to them about me during weekend working which I was not in for, so I fear what tomorrow will bring.
