The **International Association of Machinists and Aerospace Workers (IAM)** is one of North America’s largest and most diverse labor unions, representing nearly 600,000 active and retired members across over 200 industries, primarily in the United States and Canada[1][5][6]. Founded in 1888 by 19 machinists meeting secretly in Atlanta, the IAM has grown to encompass more than 2,000 local lodges and represents workers in sectors ranging from aerospace and manufacturing to transportation and woodworking[2][4]. IAM’s core mission is to ensure workers receive fair wages, benefits, and workplace dignity by uniting to claim the full value of their labor. It advocates for strong collective bargaining agreements that secure higher wages—on average 26% greater than non-union workers—and superior benefits, including pensions, healthcare, paid leave, and training opportunities[1][6]. The union emphasizes solidarity and justice, aiming to maintain and expand member protections and standards of living. Historically, IAM played a key role in labor rights advances such as the first collective bargaining agreement with a railroad company in 1892 and the fight for reasonable work hours and better wages in the early 20th century[2][3]. Its membership peaked at over one million in 1968. The union has also absorbed other labor organizations, such as the Transportation Communications International Union in 2005, and continues organizing efforts in modern industries like Amazon fulfillment centers[4]. IAM’s leadership includes a diverse executive council, with Dora Cervantes as the highest-ranking woman and first Latina general secretary-treasurer[2]. The union remains politically active, contributing to labor-friendly policies and lobbying efforts[9]. Its members include employees from major companies such as Boeing, Harley-Davidson, United Airlines, John Deere, and UPS, reflecting the union’s broad industrial footprint[4][6]. In summary, the IAM stands as a powerful advocate for worker rights and benefits in an evolving economy
