Approximately 3,200 union members at Boeing facilities in Missouri and Illinois began a strike at midnight on Monday. This action follows the rejection of a contract offer from the company. The International Association of Machinists and Aerospace Workers District 837, which represents the workers, announced the strike after local members voted against the latest proposal on Sunday.

The workers are involved in the assembly and maintenance of fighter jets, including the F-15 and F/A-18 models. Sam Cicinelli, the IAM Midwest Territory General Vice President, emphasized the importance of the workers' roles, stating, "IAM District 837 members build the aircraft and defense systems that keep our country safe. They deserve nothing less than a contract that keeps their families secure and recognizes their unmatched expertise."

The striking workers are based at Boeing facilities in St. Louis and St. Charles, Missouri, as well as Mascoutah, Illinois. This strike comes after a previous contract was rejected on July 27, which had proposed a four-year agreement.

Boeing expressed disappointment over the rejection of its offer, which included a 40% average wage increase and addressed concerns regarding alternative work schedules. Dan Gillian, Boeing's Air Dominance vice president and general manager, stated, "We are prepared for a strike and have fully implemented our contingency plan to ensure our non-striking workforce can continue supporting our customers."

The union's decision to strike highlights ongoing tensions between the workers and Boeing regarding labor conditions and compensation. The previous contract expired just before the strike began, leaving the workers without an agreement as they seek better terms.
