I've had some sort of first hand experiences with the unions. The Teamsters to be exact in Detroit. They tried to unionize my dad's Sears store.
Short story is they picketed and refused to deliver. Dad hired guys to deliver at night (scabs is what the union guys called em).
Teamsters found the trucks which were hidden in a corn field during the day and burned em all.
Dad's second in command got beat with a baseball bat on his way into the store. We got calls at the house saying that our house was next to be burnt down. Good stuff right there.
I've got some union friends and we just don't discuss it.
I've got nothing against union members as some of my best friends are just that. The organizers however seem to be evil fooking human beings.
