Sorry i know this has probably been asked before. Ive had to phone in sick because i am in pain the driving/walking is difficult, ive been told that i either take it unpaid or i have to work checkouts. I cant find this information on the oursainsburys website
Will i need to provide a sick/fit note when i return i have a doctors appointment booked but the closet one i could get was for a couple weeks time i am apart of the union but not sure if this will help my case.
many thanks in advance
