Your call, I chose option (5) and blew up any bridges
Sometimes you gotta do what you gotta do to expose the folks who believe they can run over you w/o recourse.
Had a job on a golf course for about 8 years. My egotistical cowboy wannabee boss had been there 35 years and felt it was his Kingdom/felt entitled/and felt he was above the rules. A real "My way or the highway" kinda person.
One day he exposed the crew to toxic chems and made jokes about everyone running outside ("like little girls"). Fuming inside...I simply walked away/went home. The next day he asked where I went/why I left and I told him that I went home to wash the chemicals off and was too pissed to return. He was not happy with that answer.
The next AM when I came in he motioned me into his office and told me to give him all of my keys....and that I was fired. I just looked at him and said "Do you think that's a smart decision on your part?" He laughed and boasted how he'd been there 35 years and I was simply no longer employed there.
The next day I called 3 other guys who were there/were also exposed. I asked each of them if they'd sign a letter I was going to write...TO THE EPA. 3 pages of speel and 4 sigs later...and in about 3 weeks I had 2 EPA ladies in my living room. LOFL. They were not happy.
Evidently a month or so later things got fun for him....and >>>he<<< ended up getting fired. In the interim he figured out that the Mechanic was one of the other folks who reported him and he fired him as well before he himself was canned.
When they gave him his going away party the Mechanic and I got a cowboy boot box from a local store and ONE worn out cowboy boot and wrapped it all up real nice. Inside we put a card with the sentiment "We heard you GOT THE BOOT. HERE's another from (our names) to complete your pair! PAYBACKS ARE HELL!" Nyuk. Nyuk. From all reports...he turned bright red...threw the box....and almost blew a gasket
