A Flaw in Right-to-Work Laws?

     So I was discussing the issue of unions and right-to-work laws with a more left-leaning guy and he brought up what I thought was an interesting point. He said that he too agrees that workers should have the right to choose whether or not to join a union, but that a problem with right-to-work laws in certain areas at least, is that they allow people to gain the benefits of a union without joining. That at many companies where a union is present in such states, that non-union members still get the union benefits. This I wasn't aware of, but if true, such laws might need some reform. You shouldn't be able to get the benefits of collective bargaining without joining the union; if you want such benefits, become a paying union member.
