ByJohn S. McClenahen Of the 239,361 U.S. private-sector, non-farm workers who lost their jobs for at least 31 days during the first three months of this year, only 4,633 workers, or 1.9%, saw their jobs move to foreign locations, according to a new statistical series released for the first time on June 10 by the U.S. Department of Labor. During the first quarter, loss of jobs because of domestic relocation work -- both within the company and to other companies -- affected 9,985 workers. The new statistics do not break out separate data for manufacturing and offshoring, the movement of jobs from the U.S. to other countries. Nor do the statistics include layoffs affecting fewer than 50 workers or layoffs at companies with fewer than 50 employees.
