BOEING has laid off hundreds of additional employees in Washington state and California, news outlets reported on Monday.

The move on Monday is part of planned cuts that will eventually reduce the workforce by about 17,000.

Reports say that nearly 400 Boeing employees were laid off in Washington state and more than 500 in California.

The aerospace giant announced previously it would reduce its workforce by 10 per cent in coming months as it tries to recover from financial and regulatory troubles and a strike by its machinists that lasted almost two months.

Chief executive officer Kelly Ortberg has said the strike did not cause the lay-offs, which he attributed to overstaffing.

In November, the company started notifying workers who would be laid off. Notices filed with state employment agencies showed the first round of cuts affected about 3,500 people around the country, The Seattle Times reported.

Boeing has said most laid-off employees remain on payroll for about two months and will receive severance pay, career transition services and subsidised health insurance benefits for up to three months.

“As announced in early October, we are adjusting our workforce levels to align with our financial reality and a more focused set of priorities,” Boeing spokespeople say.
