I have been with my employer for less than 12 mths and after 2 mths was sent home sick twice. The second time i was asked to come in for an informal chat and discuss any problems etc that were affecting me. After I informed them of the problems I was having they hounded at home for documentary evidence to prove it. I was signed off by the doctor with stress and received phone calls day after day from my employer. Also previous to my informal chat I was told by the HR manager that he could smell bull**** a mile off. Whilst off sick my employer has contacted my previous employer to see if I was still working for them whilst off sick, and I believe my manager also contacted her ex-assistant to enquire with a friend of mine who works at her previous employ about my illness. What can I do?
