I hate, hate unions for lots of reasons. #1 on my list are the teacher unions and I could write a book on the reasons why. I've lived through months of teamster, long shoreman, grocery, public transportation, air line, doc workers, nurse, carpenter, police, and even hospitality service strikes and protests.
I see them as an anti-American, anti-capitalist, and selfish thugocracy. They don't even produce on an exceptional level. They only promote mediocracy at a high price.
