Start with giving them this letter.
Once given to them, if you are fired, smile at the money they are going to lose in a civil lawsuit to you.
Smart employers will pass this letter to their legal council, and when their council informs them of the multitude of laws they will be violating by forcing the "vaccine", they should quickly back down.
Everybody who kneels before The Beast in the Last Days and everyone who wears The Mark will have an excuse for why they "had" to do it, won't they?
I'd say a downvote is appropriate. It sounds like your people don't rise to the occasion and prefer to bow down.
