St. Louis, Sept. 12, 2025 — Members of the International Association of Machinists and Aerospace Workers District 837 have voted to reject Boeing’s five-year contract offer. IAM continues to strike Boeing’s defense facilities in St. Louis.
Boeing’s modified offer did not include a sufficient signing bonus relative to what other Boeing workers have received, or a raise in 401(k) benefits. The union’s vote underscores the determination of approximately 3,200 IAM members to continue their strike.
Approximately 3,200 IAM District 837 members at Boeing have been on strike since Aug. 4. The Union members at Boeing facilities in St. Louis, St. Charles, Mo., and Mascoutah, Ill., assemble and maintain advanced aircraft and weapons systems, including the F-15, F/A-18, and cutting-edge missile and defense technologies. Their work plays a vital role in safeguarding national security and supporting U.S. and allied defense operations.
“Our members in St. Louis have once again shown that they will not settle for Boeing’s half-measures,” said IAM International President Brian Bryant. “Boeing must start listening to its employees and come back to the table with a meaningful offer that respects the sacrifices and skill of these workers.”
“Our members will always have the final say in their futures,” said IAM District 837 Directing Business Representative Tom Boelling. “They are standing shoulder to shoulder and sending an unmistakable message: this company cannot thrive while failing to offer a contract that our members won’t accept.”
“The message could not be clearer—our members expect Boeing to do better,” said IAM Midwest Territory General Vice President Sam Cicinelli. “They will not be brushed aside with small adjustments. Boeing needs to stop dragging its feet and negotiate an agreement that honors the contributions of its workforce.”
“This strike is about fairness, respect, and real improvements,” said IAM Resident General Vice President Jody Bennett. “Boeing has the resources to invest in its people, yet it continues to shortchange them. Our members will not back down until the company gets serious about doing right by the workers who build America’s defense.”
The International Association of Machinists and Aerospace Workers represents’ about 600,000 members.
