What does that have to do with RTW? Nothing.
I'll bite again, even though you will deny it applies. How about all the workers that don't get the full attention of their "free" representation at grievance, panel hearings? Probably lost a lot of money, and maybe jobs because of the union not fighting as hard for them. Federal law requires such. Why do you think that companies fight so hard, and spend money lobbying for RTW legislation, just so everything stays the same? Naïve.
Again, why should you get for free what the honest worker has to pay for? Wages? benefits? Vacations? I'd be ok with it if they would also get benefit package that non union workers would get, but law says otherwise. I bet they'd be willing to pay the dues if they were forced to take a $7/hr pay cut, HC cut, pension cut, etc, if not.
