FILE - In this Aug. 30, 2012 file photo, production line worker Xiao Yins-Wong straightens the wick in the candles at Chesapeake Bay Candle factory in Glen Burnie Md. U.S. workers were more productive this summer than initially thought, while costing their companies less. The Labor Department said Wednesday that productivity grew at an annual rate of 2.9 percent from July through September. That's the fastest pace in two years and higher than the initial estimate of 1.9 percent. Labor costs dropped at a rate of 1.9 percent, more than the 0.1 percent dip initially estimated.
