Boeing is taking steps to replace employees in its defense unit as a strike by 3,200 workers continues into its second month without a new contract agreement. The company is hiring permanent replacement workers for manufacturing roles to ensure they can continue supporting their customers, particularly in assembling and maintaining F-15 fighter jets and missile systems. The strike, led by the International Association of Machinists and Aerospace Workers District 837, began on August 4 after workers rejected a contract offer from Boeing.
