So I am back at work about 2 months after being in long term sick. I had booked one day a/l a few weeks ago but I got flu the day before my a/l and the day after. As I had so much a/l to take upon returning to work I asked my manager if I could take these sick days as a/l instead. I just got paid this month and I am down over £500. I'm so pissed off. She must have recorded it all as sick leave or 2 separate sick leaves. Is there anything I can do? I'm really going to struggle this month being down this much pay.
