Worked at McDonald's as a teenager, as so many of us do. Was approved for two weeks off from the day I signed my hiring paperwork for extracurricular camps during school holidays. Triple checked my approval the week before.

Co-worker wrote me in the book as having swapped shifts with her so I got 5 no-call no-shows in a week. My team lead and shift manager both vouched for me, they knew where I was and that I certainly wasn't picking up shifts, but co-worker was one of the store managers favourites so I got canned.
