United Technologies Corp., a supplier of helicopters and jet engines to the U.S. military, said an extended government shutdown would force furloughs of as many as 5,000 workers. The company is poised to lay off about 2,000 Sikorsky Aircraft employees in Connecticut, Florida and Alabama on Monday, according to a statement. Work on Black Hawk helicopters slowed after Defense Department inspectors stopped work Tuesday, United Technologies said. Another 2,000 workers would be furloughed at Pratt & Whitney, which manufactures engines for Lockheed Martin Corp.’s F-35 fighter jet, and at UTC Aerospace Systems, a maker of landing gear and flight control systems, if the shutdown lasts into next week.

September was an improvement from the previous month, but only because ADP revised its August figure down to 159,000 from the initially reported 176,000.
