The PRO Act is about as important a piece of labor legislation as we’ve seen in some time. It holds the potential to open the door for workers and organizers to step up and reverse 40 years of losses for organized labor. The law, whose initials stand for Protecting the Right to Organize, aims to do just that: protect workers from being harassed or fired if they try to organize a union or if they try to help their already existing union become more active in their workplace. This is seen as the number one legislative priority for organized labor.
