ST. LOUIS, July 27, 2025 – More than 3,200 IAM District 837 members at Boeing facilities in St. Louis, St. Charles, Mo., and Mascoutah, Ill., have overwhelmingly voted to reject the company’s contract offer during a vote held on Sunday, July 27.
IAM Union members delivered a clear message: the proposal from Boeing Defense fell short of addressing the priorities and sacrifices of the skilled IAM Union workforce. Our members are standing together to demand a contract that respects their work and ensures a secure future.
Unless a new agreement is reached, the current contract will expire at 11:59 p.m. CT on Sunday, July 27, at which point there is a seven-day cooling off period before a strike would begin.
The IAM Union remains committed to achieving a fair contract that meets the needs of our members. The IAM Union looks forward to returning to the bargaining table with Boeing’s leadership to deliver meaningful improvements that support the well-being and livelihoods of IAM members and their families.
The IAM Union (International Association of Machinists and Aerospace Workers) is one of North America’s largest and most diverse industrial trade unions, representing approximately 600,000 active and retired members in the aerospace, defense, airlines, shipbuilding, railroad, transit, healthcare, automotive, and other industries across the United States and Canada.
