Kris Warner doesn't understand unions.

As a Union member whose grandfather was a president of the AFL, and as someone with a deep loathing for my union, the ability to form unions matters not a whit compared to the utility of JOINING an existing union.

The guy talks about a decline from 30% to 11%. That's not about not being able to form unions - that's about people in unions not getting enough benefit to justify the hassle.
