3,200 highly-skilled IAM Union members at Boeing facilities in St. Louis, St. Charles, Mo., and Mascoutah, Ill. voted on Sunday, Aug. 3, 2025 to reject a modified four-year labor agreement with Boeing and are now on strike.

These IAM Members assemble and maintain advanced aircraft and weapons systems, including the F-15, F/A-18, and cutting-edge missile and defense technologies. Their work plays a vital role in safeguarding national security and supporting U.S. and allied defense operations.

Boeing has already enacted a contingency plan using non-union "replacement workers."

IAM District 837 members on strike with Boeing deserve a contract that reflects their skill, dedication, and the critical role they play in our nation’s defense. They are fighting for a fair contract that recognizes their UNMATCHED EXPERTISE.

Sign this solidarity pledge to show your support for the IAM Union members on strike, standing up for the value of their work and contribution to the company's huge success.
