RTW is inappropriately named. No one prevents you from working anywhere you want to but RTW DOES allow people to avail themselves of contract and union rights without paying for it. No one can force you to join a union. They can request you to pay your fair share. Contract negotiations are expensive. Work rules need to have some enforcement to work. Grievance representation is exceedingly laborious. Expecting those services without payment isn't right nor responsible. No one I know wants the right to work more and more for less and less.
