Formed in 1887 as the Massachusetts branch of the American Federation of Labor, and later chartered by the national AFL-CIO in 1958, the Massachusetts AFL-CIO is a union of unions, dedicated to achieving a better quality of life for working families in our commonwealth.
Today, we are the state’s largest labor umbrella organization, representing more than 750 local unions and intermediate bodies, such as joint boards and district councils. We are one of 51 state charters of our parent organization, the national American Federation of Labor and Congress of Industrial Organizations (AFL-CIO).
