ST. LOUIS — Approximately 3,200 members of the International Association of Machinists and Aerospace Workers (IAM) District 837 at Boeing in the St. Louis area have voted to ratify a new five-year contract, ending a strike that began Aug. 4, 2025. Members are scheduled to return to work Sunday, Nov. 16, 2025, at Boeing manufacturing plants in St. Louis and St. Charles, Mo., and Mascoutah.
The agreement includes a 24% wage increase over the life of the contract and a $6,000 signing bonus, according to the union representing the workers who walked off the job more than three months ago.

The machinists build fighter jets, weapons systems, and the U.S. Navy’s first carrier-based unmanned aircraft at these facilities.
“IAM District 837 members stood strong and united for over three months,” the union said in a statement. “We thank our Bargaining Committee for their tireless efforts, and we appreciate the unwavering support of our members, their families, the St. Louis community, our labor allies, and elected officials throughout this fight. We’re proud of what our members have fought for together and are ready to get back to building the world’s most advanced military aircraft. We look forward to continuing to fight for fairness and respect for the world’s best defense workers in the contracts to come.”
Boeing responded that it looks forward to “bringing our full team back together.”
The strike, while smaller than last year’s walkout involving 33,000 Boeing workers who build commercial jetliners, had the potential to disrupt the company’s efforts to regain financial stability. Boeing’s Defense, Space & Security division accounts for more than one-third of the company’s revenue.
The IAM Union (International Association of Machinists and Aerospace Workers) represents approximately 600,000 active and retired members in aerospace, defense, airlines, shipbuilding, rail, transit, healthcare, automotive, and other industries across North America.
