"Right to Work" is a BS term. It has nothing to do with the "right to have a job". But you know what? As long as we need money just to survive on this planet, and that is the prevailing way to get the basics for staying alive, jobs will be necessary for all... so in a way, you could say that yes, everyone has the right to a way to get the resources necessary for basic survival. Depends on how you look at it.
So I would have a right to work in a union state?
No, I have to join the damn union where they take my dues and give them to ONE PARTY only in campaign contributions.
