I am on sick leave at the moment, GP has signed me off for 4 weeks, am having MH issues which are ongoing. Manager wants to have a weekly call with me whilst I am off. I genuinely feel like it will be detrimental to my MH, would prefer to be left alone, just thinking about speaking to them is making my anxiety worse. I am happy to have a chat before I go back to talk about support, return to work etc. But really don't want to now. Am I within my rights to say no to the weekly Teams meeting?
