Members of the International Association of Machinists and Aerospace Workers (IAM) District 837 have voted to reject Boeing’s latest five-year contract proposal, opting to continue their strike at the company’s defense facilities in St. Louis. The strike, which began on August 4, involves approximately 3,200 IAM members who work at Boeing locations in St. Louis, St. Charles, Missouri, and Mascoutah, Illinois.
Union members cited concerns that Boeing’s modified offer did not provide a sufficient signing bonus compared to other Boeing workers or an increase in 401(k) benefits. These issues led the workforce to maintain their stance for improved terms.
IAM International President Brian Bryant stated: “Our members in St. Louis have once again shown that they will not settle for Boeing’s half-measures. 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.”
IAM District 837 Directing Business Representative Tom Boelling commented: “Our members will always have the final say in their futures. 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.”
IAM Midwest Territory General Vice President Sam Cicinelli added: “The message could not be clearer—our members expect Boeing to do better. 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.”
Jody Bennett, IAM Resident General Vice President, said: “This strike is about fairness, respect, and real improvements. 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 union represents around 600,000 active and retired members across various industries including aerospace, defense, airlines, shipbuilding, railroad, transit, healthcare, automotive sectors throughout North America.
