There was some Liberal blogger a few years ago who “went undercover” and took a job at Walmart to write an expose on the horrible mistreatment of workers there.
After about a month on the job she was forced to concede that, given what the job was, working conditions were actually pretty good.
From my sources, one is required to check the schedule daily as hours will change and you can be blamed for that. Kind of a pain if you ask me. They tend to ask a lot from what I hear.
