I started working at 15. The owner/manager of my first job would give the 15-17 year-old girls he hired drugs in exchange for sexual favors. Also had us work past legal hours and all the other normal exploitative shit people should expect.
Second job I had also had pedo managers. Asking us questions like, “what was the craziest places you had sex at?” during group orientation. I also had to dispute the hours I was paid for on nearly every paycheck I got.
I’m guessing experiences like this aren’t universal, but the fact that my first 2 jobs as a child were very exploitative, it’s probably not uncommon.
I think scheduling and being on time could be picked up quickly by adults.
