ST. LOUIS: More than 3,200 Boeing workers across key manufacturing plants in the Midwest began a strike on Monday after rejecting a proposed four-year labour contract. The walkout affects facilities in St. Louis and St. Charles, Missouri, as well as Mascoutah, Illinois—locations critical to Boeing’s military aircraft and weapons production.
Members of the International Association of Machinists and Aerospace Workers (IAM) voted on Sunday to reject a revised contract that included a 20% wage increase and $5,000 ratification bonus but failed to meet their core demands on scheduling and job security. The strike follows a one-week cooling-off period after an earlier version of the agreement was also declined.
“IAM District 837 members build the aircraft and defense systems that keep our country safe,” said Sam Cicinelli, general vice president for IAM Midwest, in a statement. “They deserve nothing less than a contract that keeps their families secure and recognises their unmatched expertise.”
Boeing had anticipated the strike after workers rejected the latest offer, which did not further increase wages but removed a controversial work schedule clause that would have impacted overtime earnings. The company stated it has enacted contingency plans to maintain operations with non-striking staff.
Dan Gillian, Boeing Air Dominance VP, expressed disappointment: “We’re disappointed our employees rejected an offer that featured 40% average wage growth and resolved their primary issue on alternative work schedules.”
The Boeing Defense, Space & Security division contributes over one-third of the company’s revenue, making the strike significant but not as disruptive as last year’s walkout by commercial jet builders. CEO Kelly Ortberg assured analysts the company is prepared to manage the impact.
