The background is I have never been furloughed and have worked through lockdown, often doing other jobs just to help my boss out (small firm). I did have Covid symptoms and was diagnosed with suspected Covid by at least 3 different doctors. I felt really ill at times but worked as much as I could from home, taking breaks when I was really tired. Anyway, been back at work since June. Over the past few weeks I have had some really bad migraines - to the point of almost fainting. I was given a sick note by the Doctor for a week but only used two days of it. I went back to work for a day and a half and was violently ill again. To cut a long story short I have been working my lunches and working late almost every day since I came back. I don't have a break at all - I sit at my desk all day (at work) and pretty much only move to go to the toilet. I have been putting in overtime for these hours which goes to the accountant. I do a lot of hours that I don't put in - especially if I have been ill. Anyway I had put down about 4 1/2 hours over time each week on average. None of this was as a result me being ill because I made a point of trying to make those hours up. I even did pretty much a full day on the Saturday after being off to try and make up. Anyway my boss has now questioned the overtime and he's pretty hurt by it for some reason. He said I had been off a few times (I agreed) because of migraines (which doctor diagnosed as stress induced). He thinks I have been taking the piss. He sees me working these hours by he way. I also often take work home or start e-mailing at 8 in the morning before I leave for work (don't put these hours down). We are extremely busy at he moment and I told him weeks ago I was feeling overwhelmed - he couldn't really see the issue. I have worked there for many many years and I am hurt that he would think I would try and screw him for money - I just couldn''t do it. AIBU for putting in the extra time?
