I have been the victim of harassment at work by my manager, I followed the grievance procedure and this resulted in my boss being given a written warning last week. As a result of this whole episode my GP has signed me off work for 2 weeks with stress. My boss now has emailed me saying he's arranged a meeting to 'discuss issues to perhaps aid my recovery' but I don't feel like I want any contact from the company and want to be left alone to recover. Have I any rights here, do I have rights not to attend or to be contacted my the company whilst I am off work?
