Wisconsin Gov. Scott Walker meanwhile has signed a so-called right-to-work bill, striking a blow to organized labor four years after he gutted collective bargaining rights for public sector workers. Labor groups had staged mass protests against the bill, which makes Wisconsin the 25th “right-to-work” state. The bill Walker signed was taken practically verbatim from model legislation proposed by the right-wing American Legislative Exchange Council. It bars the mandatory collection of union dues, but critics say it is a wholesale attack on collective bargaining power.
