It doesn’t say where op works, it’s not necessarily a desk job. I worked as a stocker in a big store and one day I got written up for going “missing” even though I was working hard.

I was the assistant manager at a movie theater for a few years. Part of my job, in addition to working concessions, was to do office work like inventory orders or loading the movies to the projectors. If I wasn’t helping concessions, I’d sometimes get a talking to, but they also didn’t really like me staying after my shift to get the work done. When I finally left the job (I was having issues with some coworkers publicly not respecting me), my boss said I would’ve been a perfect personal assistant if she could have afforded it.
