I had a meeting about my sickness with my manager today...she has previously said that there are no issues as I have a recognised health problem but now she is saying that I need to go to a company-appointed doctor for a second opinion, which isn't an issue for me as I have nothing to hide.
Although I have said that I will go, management have dragged their feet getting it arranged and I have been ill again before I could attend the appointment (date still to be arranged) and they have now given me a formal warning despite my health problems and without waiting for the second opinion which they are insisting on. I asked why I was being singled out and she said that I could make a complaint if I wanted but insinuated that she would make things very difficult for me should that happen. I have no doubt that she was saying that as a threat.
I don't want to cause trouble but I don't know what to do next....there is no point making a complaint as our company has a history of ignoring/not dealing with complaints (one manager has 6 serious complaints under his belt and no disciplinary action has been taken- he brags about it all the time!) and HR have confirmed that once the second opinion has been received, the formal warning may well be removed but I don't know if this is enough as nothing has been confirmed in writing....has anyone else been in this situation and, if so, what have you done?
