Nonfarm private employment in the U.S. decreased by 8,000 from August to September, according to data from the ADP ( ADP) National Employment Report released Wednesday. The estimated change from July to August was revised downward from a decline of 33,000 to a drop of 37,000. September's report continues to offer evidence of a weak labor market, ADP said in a press release. The report, the company said, doesn't reflect two factors that might have further depressed employment last month -- the continuing machinists' strike at Boeing ( BA) and jobs lost as a result of hurricanes that hit the Gulf Coast. The loss in jobs was driven by the goods-producing sector, which surrendered 72,000 workers in September. The manufacturing sector specifically shed 48,000 jobs. However, the service sector had a gain of 64,000 jobs. On Friday, the Labor Department will release its monthly numbers for U.S. payrolls. Analysts expect that report to show a much steeper drop than the ADP figures.
