WASHINGTON (AP) — During the 43-day U.S. government shutdown, investors, businesses, policymakers and the Federal Reserve were groping in the dark for clues about the health of the American job market. The federal workers who collect data on hiring and unemployment had been furloughed and couldn’t do their jobs. Now that the shutdown is over, the Labor Department will finally let a little light in Thursday, releasing jobs numbers for September — nearly seven weeks after they were due.
