I use to work in a warehouse where there was a lot of unfair labor issues going on. I would have a friend of mine make calls to the gas company for gas leaks, electric company for damaged wiring, fire department, etc about potential threats to the warehouse facility I'm working at. Sure enough, it caused quite a stir. My boss was really upset and production eased up due to the commotion. It was fun seeing my boss get drilled like that.
