Boeing workers in the Seattle region have decisively rejected the U.S. aerospace giant's latest contract offer, extending their nearly six-week strike.

Almost 64 percent of the members of the International Association of Machinists and Aerospace Workers District 751 rejected the contract, the union said on X.

Boeing workers in the Seattle region voted 96 percent in favor of a strike last Thursday night, halting production of the company’s best-selling airplane at a time when Boeing is facing chronic production delays and mounting debts.

Union members react as Aerospace Machinists District 751 President Jon Holden (out of frame) announces that union members rejected a proposed Boeing contract and will go on strike, following voting results at their union hall in Seattle, Washington, on Sept. 12, 2024.

Boeing announced that it has halted flight testing of the 777X after finding a failure in a structure on one of the wide-body aircraft.

The company said it discovered the damage to the custom part, which it said is located between the engine and the propeller, during scheduled maintenance. It has since grounded the other three aircraft in its test fleet.
