So-called “right-to-work” laws, while sounding like a grassroots campaign to help employees, are actually not worker-friendly. These laws don’t actually protect anybody’s right to work—they’re merely bans that prohibit labor unions from forging agreements with employers mandating that everyone working for that employer must be a union member.

Critics of “right-to-work” laws point out that they weaken unions and lead to decreased wages. In fact, a 2011 study of RTW states and non-RTW states showed that the biggest difference between workers in the two categories was that average and median wages were significantly higher in non-RTW states (by as much as 16 percent).

Now, Elizabeth Warren is attempting to repeal these “right-to-work” laws by introducing a bill called the Protecting Workers and Improving Labor Standards Act. Other senators and congressmen have joined her:

Congressman Brad Sherman, in a post on his website, declared his involvement in the bill, and added further that RTW “encourages a race to the bottom, as states compete to attract employers by offering weak labor laws and, as a result, lower wages.” Sherman affirms his commitment to stronger unions, ones that don’t have to support “free riders” who receive the benefits of the union but don’t pay any dues.
