The bulk of the job cuts are in Washington and are part of the company's plan to trim its workforce by 10% after a bruising strike.

Boeing will lay off more than 2,500 workers in the U.S. states of Washington, Oregon, South Carolina and Missouri, according to federally required filings posted on Monday and a union official, as part of the debt-heavy U.

Boeing has delivered layoff notices to more than 400 members of its professional aerospace labor union, part of thousands of cuts planned as the company struggles to recover from financial and regulatory trouble as well as an eight-week strike by its machinists' union.
