At my last job(not tech), our wages were negotiated with the union at a much lower rate than our competitors and owed dues. We had no control because the union was "representing" us and we could take it or quit.
If this goes though, can we sure car, knife, and anything else manufacturers? They sometimes use shady lots to sell cars, don't tell me everything about the car, and I can run someone over. Many people die each year from cars!
This case might be precident...
