Messing with an abusive supervisor.
This was over a quarter of a century ago. Yes, I'm old. I was working as a truck driver and I had several runs ins with a warehouse supervisor who made up petty rules to mess with the warehouse staff which meant we had a crazy staff turnover. I had complained about him to the managers repeatedly. Note there was a driver shortage, especially of those with ADR (hazardous goods permits) that has never really got better.
His favourite thing was to screw with staff and make sure their days were miserable. He also tried it with the drivers by "forgetting" to tell the schedulers about urgent pick ups.
I was the last driver back, had called my wife to tell her I would be home soon, when he told the traffic controller about a pick up of four small bins of bolts (two head sizes, with two lengths) from a manufacturer that needed to be loaded onto an early morning run the next day. They could have told me about the pick up earlier. It was 30 minutes away from the yard but was on my way back from my route.
I got back after the pick up and he starts crowing about how he screwed up my evenings plans. All the warehouse staff but him had gone home. I walked into the General Managers office and told him what had happened. His response was a shrug so I told that I was going back to my truck to get my kit.
I opened the side curtains, unstrapped the load and shouted the manager and warehouse supervisor over. I told the manager that he allows the supervisor to bully people to screw with their lives, you can live with the consequences. I jumped in the cab, reversed hard, and stamped on the brakes, tipping the four small bins of bolts up the trailer. "You can sort the bolts out, and you can stick your job up your arse", got out of the cab and clocked out.
I called an agency and started in a new job the next day. One of the other drivers called and told me it took them two hours to sort it out.
Was anyone hurt? No. Just they got a taste of their own medicine. Was it petty, hell yes.
