I’ve worked at a few places that don’t treat employees fairly. I’m sure most people have. It’s just part of life now days. Personally, I have rarely ever been mistreated in the workplace. It’s happened, just not enough to impact my decision to stay or leave that job.
All of my previous jobs I’ve quit because of money, (Fast food doesn’t pay much) or time constraints (hard to work full time when you’re a full time student). Never has my reason for leaving a job stemmed from an issue I had with my employer.
