I have bipolar and am currently signed off with it as I've gone into a mixed episode. My employer knows I have bipolar and I have provided a sick certificate. I attended a meeting with my employer the other day, it was a finding of an investigation into a complaint against me - I know I didn't have to attend whilst on sick leave but I chose to in order to get it over with. Before she told me the findings she started questioning me on how I was feeling. I didn't want to elaborate other than to say 'not well'. She was adamant she had the right to ask me and that I should answer her. I don't think that's the case but am I wrong? Surely while I'm off sick the details of how I feel etc are none of their business?
