I worked for a company that made cement pipes. They decided to screw me on hours and pay, so I got even the best way I knew how!
I called the health department, Department of environmental Quality, DEA, FBI, fire marshal, OSHA, Immigration, child protection and a bunch of other places and had the boss and a few lower level supervisors investigated both at the company and at their homes.
They got in a lot of trouble. I know, because some of the agencies called me back and told me they were shutting the company down.
