As usual, I'm late to the little party you folks are having. I'd like to offer a link that I'd like to share, and you'll see some of my comments after the link as well.

I'll restate some of those comments more generally.
I grew up in a union household (International paper workers), but my dad was not a true union man. He saw that there were times when, what the union wanted, was going to put too heavy of a burden on the company, forcing them to non-competitiveness. This was in the late 1980's and early 1990's, so our little squabbles here aren't new issues. Strikes and union vs. company arguments aren't something that was just invented with the teachers and workers in Wisconsin. The public employee unionization tiff is, however, a nice new wrinkle on things.
So, with that background, understand that I work in a white collar profession where NO ONE unionizes, and in fact, unions are looked down upon. What my co-workers who are so enlightened as to the harm that unions do, don't realize, is that they are being marginalized as well. They might be making an adequate amount of money. But that's only because of the efforts that unions made in the past, in industries not related to mine.
So, in a VERY RED STATE, I am decidedly blue, and strongly in favor of unionization. I don't agree with all parts of collective agreements. YES, there are blatant abuses, and a skeptical eye must be kept on those little clauses slipped in at the last minute, a la our fine state politicians methods. Funny.....the people of Alabama benefitted the most by Democratic ideals and unionization in the Northern states.
Those gains helped this state out of the stone ages. however, because of political propoganda, most Alabamians believe they are Republican. I'd laugh, but it hurts so much, it's just easier to cry.
