Members of the International Association of Machinists and Aerospace Workers (IAM) District 837 have voted to reject Boeing’s revised five-year contract offer, opting to continue their strike at the company’s defense facilities in St. Louis.
The union stated that Boeing’s latest proposal did not meet expectations for a signing bonus or increases in 401(k) benefits. The vote reflects the ongoing determination of about 3,200 IAM members who have been on strike since August 4.
IAM District 837 members work at Boeing sites in St. Louis, St. Charles, Missouri, and Mascoutah, Illinois. They assemble and maintain military aircraft such as the F-15 and F/A-18, as well as missile and defense systems used by U.S. and allied forces.
“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 around 600,000 active and retired workers across various industries including aerospace, defense, airlines, shipbuilding, railroad, transit, healthcare, automotive sectors in both the United States and Canada.
