ST. LOUIS, Aug. 3, 2025 – Approximately 3,200 highly-skilled IAM Union members at Boeing facilities in St. Louis, St. Charles, Mo., and Mascoutah, Ill. voted on Sunday, Aug. 3, 2025 to reject a modified four-year labor agreement with Boeing.
This vote follows members’ overwhelming rejection of Boeing’s earlier proposal on Sunday, July 27. A strike will begin at midnight on Monday, Aug 4.
“IAM District 837 members have spoken loud and clear, they deserve a contract that reflects their skill, dedication, and the critical role they play in our nation’s defense,” said IAM District 837 Directing Business Representative Tom Boelling. “We stand shoulder to shoulder with these working families as they fight for fairness and respect on the job.”
“Our union is built on democracy, and our members have every right to demand a contract worthy of their contributions,” said IAM International President Brian Bryant. “We will be there on the picket lines, ensuring Boeing hears the collective power of working people.”
“IAM District 837 members build the aircraft and defense systems that keep our country safe,” said IAM Midwest Territory General Vice President Sam Cicinelli. “They deserve nothing less than a contract that keeps their families secure and recognizes their unmatched expertise.”
“Solidarity is our strength. This vote shows that when workers stand together, they can push back against corporate greed and fight for a better future for themselves and their families,” said IAM Resident General Vice President Jody Bennett. “We are proud to back our members every step of the way.”
IAM Members 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.
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, railroad, transit, healthcare, automotive, and other industries across the United States and Canada.
