I have name changed for this. I don't want to go into specific details because it is very outing. Anyway the upshot is that a woman at work in a senior position (not my boss) was extremely rude and bullying to me yesterday. I have worked in the same office for over 30 years - her about 15. My own boss is currently on holiday. Originally my boss was going into the office alone during the pandemic. I had symptoms of Covid and was unable to go in (I live locally) but when I was out of quarantine I went in to assist (wasn't asked to). I could tell he was struggling. During this time I did a lot of jobs that weren't mine to help out whilst the rest of the staff were either furloughed or working from home. The lady in question only came back to the office yesterday although others have been back for weeks. I felt that as we are a small office and that as I had assisted a lot and actually helped her do her job from home by scanning stuff that we might have a more cordial working environment. However, an incident occurred yesterday and I mentioned that I had done a lot of tasks outwith my comfort zone to assist. Her reaction was woe is me and basically she couldn't give a toss. I wasn't trying to be a martyr. I have been working a lot of overtime because things in my own job have suddenly become manic and as my boss is off I am working an extra 3 hours or so a day - including working lunch - no one else is doing this. I am doing it for my own benefit because I wouldn't be able to catch up. I don't want to ramble on but advice please on how I should proceed. I actually feel like handing in my notice I am so upset with the attitude of the staff who haven't been in. I did calmly explain that I didn't appreciate her tone or her bullying behaviour and would appreciae that she did not speak to me like that in future.
