I have a medical issue that occasionally causes me to need a day off of work.I always provide the doctors note or restrictions and didn't think any more of it, then out of nowhere was written up! I asked why because I had provided a physician excuse and they didn't know what to say. I was under the impression that the doctors note would provide me an excused absence. When I would produce these notes no one had said any different. Does this sound right? I was given the paperwork without my union rep present (because I didn't know any better) and now wish I wouldn't have signed it.
