Aerospace giant Boeing is adding to the growing list of U.S. companies that are slashing jobs as profits plummet. The world's second largest maker of commercial airplanes said Wednesday it will cut 10,000 jobs this year - about six percent of its global work force. Earlier, Boeing announced it lost $56 million over the last three months of 2008, because of a workers' strike and delays in the production of the company's new, highly touted 787 jetliner.
