Dec. 3 (UPI) -- ADP said Wednesday that small businesses and private companies were hit hardest in November by a slowdown in the U.S. labor market. The private payroll processor's monthly employment report indicated some 32,000 were shed by private employers. It said job creation had been "flat" during the second half of this year with pay growth on a "downward" trend. "Hiring has been choppy of late as employers weather cautious consumers and an uncertain macroeconomic environment," said ADP
