I was on annual leave for a month and I was overseas during my leave. For few weeks before this, I had a medical issue and was under treatment. I met the doctor again before leaving to overseas and I happened to get a medical certificate which stated I will be unfit to work for few days. The certificate was issued on the day I met the doctor but the days he mentioned I would be unfit to work was starting 4 days later. The reason was there were public holidays in between. My employer contacted the doctor and the doctor has put everything back on me, that I asked for the certificate and that he had asked me to come back after public holidays. All these didn't happen. The doctor has revealed things about my sickness and things I told him in the during the appointment to my employer. What can I do in this scenario? Can I file a case on the doctor for revealing my file details. Is the certificate valid or invalid? Can the doctor file a case on me for not mentioning my annual leave to him. Can he file a case on me for misleading? These are what my employer told me that there are possibilities to happen.
