Here in America, Unions are a good bit different. Businesses where Unions are dug in, in order to work at the company you MUST be in the Union. It's not an "option." The Union won't even let you in the door unless you have connections, are willing to pay up, etc. It's basically blackmail. Unions had their place after the Industrial Revolution, but now here in America, they are like strong-arm mafia. The real reason US Companies are up and moving away to Canada, Mexico, South America, or even Union-optional southern states? Unions and their constant demands for outrageous wages for menial labour, high pension costs (pyramid scheme!) and constant bullshit. I know, I live in York, PA....once home to a mighty Caterpillar plant, and also one of the Harley-Davidson assembly plants. Caterpillar up and LEFT around 1989 after suffering years of strikes and BS from Unions. Left for Tennessee. Harley Davidson has shrunk the York plant to a shell of it's former self, and sub-contracts out tons of work to non-Union shops in the area. Unions today only give a crap about lining their coffers, and to HELL with the Members. When Caterpillar left, it didn't hurt the Union reps and management, not one bit!
The 25-yr old Union member in this story probably values her job over Union BS. She needs to eat, and doesn't buy the Union's propaganda and strong-arm tactics. (the irony!) I'm sure she'll be getting a nice friendly visit from her Union rep anytime now about her lack of support.
