Boeing will cut 17,000 jobs ¡ª 10% of its global workforce ¡ª delay first deliveries of its 777X jet by a year and record $5 billion in losses in the third quarter, as the U.S. planemaker continues to spiral during a monthlong strike.

CEO Kelly Ortberg said in a message to employees that the significant downsizing is necessary ¡°to align with our financial reality¡± after an ongoing strike by 33,000 U.S. West Coast workers halted production of its 737 MAX, 767 and 777 jets.

¡°We reset our workforce levels to align with our financial reality and to a more focused set of priorities. Over the coming months, we are planning to reduce the size of our total workforce by roughly 10%. These reductions will include executives, managers and employees,¡± Ortberg¡¯s message said.
