that’s completely disgusting. How awful for you. If you are signed off by a doctor they should not be contacting you. I would say a quick check in nearer the end of your sick leave just to see where you are in terms of returning to work, but for the rest of the time you should be left alone.I had a bad breakdown last year, went to the doctors and was signed off for two weeks, my work begrudgingly accepted it but i was still hassled every other day asking if i was “well yet“ or if i knew when i was coming back, even though they had my form from the doctors. When i went back after the two weeks my managers response (who was SO horrible) was “put a smile on your face and try to cheer up or you can just leave today if you want, we need happy people in this company” i did leave a while after that.
bet that manager wouldn’t want to be treated the way they treated you if they went through something similar. Some people are so cold and uncaring. I hope you’re in a better place now.
