International Association of Machinists and Aerospace Workers

What International Association of Machinists and Aerospace Workers does

The International Association of Machinists and Aerospace Workers (IAM) is one of North America's largest industrial trade unions, founded on May 5, 1888 in Atlanta, Georgia by 19 railroad workers and now representing approximately 600,000 active and retired members across the United States and Canada. The IAM is a non-profit labor organization governed by its membership through elected officers led by International President Brian Bryant, and is structured into territorial organizations (Eastern, Midwest, Southern, Western, Canada, Air Transport, Headquarters), local lodges, and district offices. Its affiliated bodies include the Transportation Communications Union (TCU/IAM) covering railroad and transit workers and the National Federation of Federal Employees (NFFE) covering government workers; the IAM is affiliated with the AFL-CIO and IndustriALL Global Union. Revenue is generated almost entirely through recurring member dues, with per-capita amounts set locally and not publicly disclosed.

The IAM's product portfolio centers on representation services rather than technology. Core offerings include collective bargaining and contract negotiation representation, grievance handling, strike coordination, legal advocacy (including NLRB complaints and Unfair Labor Practice charges), and member benefits — the IAM Journal (award-winning magazine), iMail email newsletter, IAM Mobile Spaces app, the Winpisinger Education and Technology Center (training facility in Hollywood, MD), the IAM 401(k) retirement plan, IAM Healthcare Benefits via the Benefit Trust Fund, and a Retiree and Medicare Resource Center (Humana partnership). The union does not develop proprietary technology platforms; its digital tools are standard communications infrastructure. Members are organized vertically across aerospace/defense (Boeing, Lockheed Martin, Leonardo DRS), airlines (Air Canada, Spirit, Lufthansa Technik Puerto Rico), railroad/transit (Long Island Rail Road), manufacturing (Whirlpool, Olin Winchester, Stanley Black & Decker, Roseburg Forest Products), retail (Apple Towson), healthcare (KU Health System pharmacy technicians), and rideshare (Massachusetts App Drivers Union).

Distribution is conducted through the IAM's field-based network of local lodges and district offices rather than commercial channels. The union's go-to-market is community/organizing-led, relying on worker mobilization, collective action, and political advocacy. Recent strategic activity centers on major contract negotiations and labor actions at Boeing (~33,000 strikers in 2025), the first LIRR strike in three decades (May 2026, ~3,500 workers across a five-union coalition), Apple NLRB complaints over the Towson store closure, the Massachusetts rideshare unionization (~70,000 drivers with 32BJ SEIU), and cross-border USMCA labor advocacy with the United Steelworkers and Mexican unions.
