Since when do shift workers need to wait for permission before leaving once their shift ends? Are you going to pay overtime? No? Okay, bye then!
When redditor u/Brooklynisqueerr gave their manager a heads up once their shift had ended, OP was rightfully confused when their manager seemed angry and annoyed. She even made up a new rule on the spot: «Next time you need to wait for a manager to let you go home.» Instead of fighting with the boss, OP complied…maliciously.
