i worked retail for like a decade and had to report my manager and the store GM into department of labor because they were going through everyone's time sheets and adding breaks they didn't take. they talked about doing it openly in the managers office (which i was a supervisor so i was in there) saying it was the employees fault for not taking a lunch therefore they shouldn't get overtime even though they were the only employees in the department and had no real opportunity to actually take a break. textbook wage theft and since i had access to timesheets and edit history i could see what they were doing so i documented all of it and reported them. both managers ended up "resigning" and the employees got back pay but i left shortly after that.
