This is one I never understood. I used to work for a lovely little supermarket called Asda. You know, tiny place, barely any staff (obviously joking, it was a massive store with 100s of staff) I took a day off because I was really ill, could barely stand or walk and could hardly even talk and it was like an interrogation like 'oh, are you sure' 'you could just sit down' etc etc. And I was like...you what?! And then the next week I came back and they took me AWAY FROM THE JOB I WAS DOING to do a 'back to work interview' in which I think MI5 must've been waiting outside because I thought I was getting done for a murder. I could still barely talk at this point too btw. They wanted all the intense details of my illness and what specifically was wrong with me. And the 'manager' got the calendar up and went 'oh this looks strange doesn't it' because I was off 6 MONTHS EARLIER around the same date and he suggested I 'ask someone to cover my shift next time'. I only worked every Saturday anyway! After that I didn't take a day off again, I went in feeling like death but I couldn't face the anxiety of that interview ever again. I was absolutely terrified of being ill or needing time off, a 'higher up' manager had to tell me to take my holidays because I was so scared of having any time off (yes, even authorised holidays). How do companies get away with it? Supermarkets and shops especially, it's so unnecessary and intimidating.
