In this July 9, 2012 photo, construction workers continue work on the job in Boston. U.S. service companies, which employ 90 percent of Americans, grew at a slightly faster pace in July. The Institute for Supply Management reported Friday, Aug. 3, 2012, that its index of non-manufacturing activity picked up slightly last month with a reading of 52.6. That was a tiny improvement from June's reading of 52.1, which had been the lowest since January 2010. Still, any reading above 50 indicates expansion. (AP Photo/Elise Amendola) less
