My colleague is constantly having time off. She even got a full day off to collect her cat from the vets in the morning 
She had a whole day off once for a hospital appointment, which obviously is fine. Except she then meets everyone after work for drinks and to show off having had her nails done earlier that day.
She even commented that it was weird to do a whole week as she hadn't done one in so long.
I have an appointment tomorrow at 10 and I'm expected to come in before and straight after. I'd be fine with that but seems it's one rule for one etc aibu?
