We thank our Bargaining Committee for their tireless efforts, and we appreciate the unwavering support of our members, their families, the St. Louis community, our labor allies, and elected officials throughout this fight. We’re proud of what our members have fought for together and are ready to get back to building the world’s most advanced military aircraft.
We look forward to continuing to fight for fairness and respect for the world’s best defense workers in the contracts to come.”
