You're a better man than I am. As a young teen on my way home from my first job, after I declined to join the union, two union goons cornered me. They gave me a choice - go back and quit immediately or get both my arms broken. I turned around and quit, which I considered a loss, although a sensible loss. It still angers me, and I still hate unions with the passion I reserve for pure evil (which seems to be a large fraction of the democrat party today).
Note: I got fit and trained up, and I have never lost or backed down since then.
Good for you
