Key Takeaways:

Over 3,000 unionized workers in Boeing's defense division went on strike after rejecting a tentative four-year contract offer.
The International Association of Machinists and Aerospace Workers (IAM) members voted down the deal, seeking a contract that better reflects their skill and dedication, despite Boeing reporting the offer included 40% average wage growth.
This strike, the first for Boeing's defense segment since 1996, affects plants in St. Louis and St. Charles, Missouri, and Mascoutah, Illinois, which produce critical defense aircraft and missile systems.

Over 3,000 unionized workers in Boeing’s defense division walked off the job Monday after voting to reject a tentative four-year contract with the aerospace manufacturing giant.

A St. Louis-based branch of the International Association of Machinists and Aerospace Workers (IAM) announced the strike in a statement over the weekend. The union did not say what specific contract provisions its members objected to or what concessions they hope to win from their employer.
