I've heard stories from people working in retail/restaurants where the owners would watch the cameras from home and call in on the landline to bitch out employees when they do something wrong. Their churn rate was abysmal.
When the boss lady showed up she tried to neg us on the work that was already done. She threatened to show us how lazy we were working on the cameras and that is why she was only going to pay us 2/3 of what we agreed on. We never took any breaks so it was pure insanity.
Thankfully the experience has him working way harder in school! No wonder there is a labor shortage; the beatings will continue untill moral improves!
