US aerospace and defence giant Boeing says 10,000 of its workers will lose their jobs in 2009 as it takes stock from the global slowdown.
The job losses, 4,500 of which had already been announced, represent six per cent of the firm's workforce.
"The global economy continues to weaken, and it's affecting air traffic and financing," said Boeing chief executive officer Jim McNerney.
"We must prepare the company, including being more aggressive in terms of productivity."
Mr McNerney, who said the job cuts were response to last year's strike action and in anticipation of future cancellations, made the announcement as the company's fourth quarter results were unveiled.
Boeing made a net loss of $56 million (£39 million) in the final quarter, compared to a $1 billion plus profit in the corresponding period one year previously.
Last year Boeing was stung by a 58-day walkout by up to 27,000 machinists, preventing the delivery of 70 of its planes.
The company continues to contend with increased development costs from its 787 Dreamliner, which is now two years behind schedule.
According to a count by Bloomberg, more than half a million jobs have been lost in the United States since Barack Obama won the presidential election in November.
The president is currently trying to push through his financial stimulus plan in Washington.
