What's wrong with "right to work" is that the core value of collective bargaining is that many powerless individuals gain power through numbers. "right to work" eliminates those numbers.

That's the theory, anyway.

Here's what I know - I worked a non-union show in a right-to-work state that flipped but because of the rules, despite my 8-year IATSE local membership the rules shoved me into the International. So all my friends that had a mailing address in California made twice as much as me, got four times the money marked into their pension, and got their hours counted. Meanwhile, the fuckin' International mandated that I needed to buy into a $1500/mo insurance policy unless I opted out through two notarized certified mail letters that had to be overnighted.

And that was with my local going to bat against my international. Without the local, the International would have actually ended up taking my money for a duplicate insurance policy that I couldn't have opted out of.

That's an effect of right-to-work - competing unions get to fuck you harder. At least with a Union state there are fewer sharks chewing on your toes.
