Yesterday, the Major League Baseball Players Association (MLBPA) became the 58th affiliate of AFL-CIO. President Liz Shuler welcomed the MLBPA to the federation: “The MLBPA and every single one of its 1,200 players have a home in our movement because this union understands and lives the meaning of the word solidarity by leveraging the power of sports and helping others. Together, with our 12.5 million members, we will bring our strength to their fights, including working to organize 5,400 minor league players.”
