Approximately 6,000 members of the Machinists (IAM) Local 839 at Spirit AeroSystems voted to ratify an improved four-year contract. The IAM members went on strike on June 24 and will return to work on July 5. The new contract includes significant improvements over the previous offer—which was rejected—including wage increases, improved prescription drug coverage and better overtime rules. The IAM members work at the Spirit AeroSystems plant in Wichita, Kansas, manufacturing major aerostructures for companies such as Boeing and Airbus, as well as defense and business jets.
