about us

The International Association of Machinists and Aerospace Workers (IAMAW) has almost 600,000 active and retired workers, making it one of the largest labor Unions in North America. 

The Union is also incredibly diverse. Members can be found in hundreds of different industries, from aerospace to woodworking, in both billion-dollar corporations and the federal government. 

The IAMAW counts employees at some of the largest and most-recognized companies in the world — including Boeing, Harley-Davidson and United Airlines — as its members.

The IAMAW’s History, Structure and Leadership

The IAMAW was founded in 1888, when 19 machinists met in a locomotive pit at a factory in Atlanta. In the 130 years since, the organization has grown to more than 2000 locals and helped win landmark rights and benefits for its members time after time. 

The Union is divided into seven territories by both geography and industry. The organization’s headquarters is located in Maryland, just outside of Washington, D.C. The headquarters is responsible for coordinating organization efforts across the entire union as well as the Union’s Woodworker Department and the Government Employees Department’s affiliated local lodges.
