I totally underestimated how ill I was going to be this last Sun/Mon when I came down with a weird case of what I have to call the flu. Basically I've been off from the Monday to Friday, without seeing a doctor. My doctors is crap. I am due and hoping to go back on Monday. I understand they will count the first Sunday as the first day off which makes the Friday the sixth day. If I say the Sat is day 7, then Sunday I was better, is that ok for self cert purposes? Or do I have to arrange a fit note?
