From AFL-CIO Blog

Hat tip to Gawker’s Hamilton Nolan (also a new member of the Writers Guild of America, East), for lifting up the latest research that shows union members earn more money than their nonunion counterparts.

Nolan writes:

On a very basic level, unions are a mechanism that allow workers to get a larger portion of the money generated by a business for themselves. Absent an organized workforce that is able to assert its power through collective bargaining, that extra money tends to go to executives and managers at the very top of a company, or to outside investors, rather than to the mass of workers.

Check out this nifty chart from The Century Foundation report that shows the lifetime cost of not joining a union.
