NEW YORK (AP) â¿¿ Superstorm Sandy is still affecting hiring at small businesses. A survey by the National Federation of Independent Business released Thursday shows that nationwide, the number of workers in small businesses fell by 0.04 workers in November. In October the number rose by 0.02 workers. NFIB Chief Economist William Dunkelberg called Sandy's impact on hiring "substantial." The results are in line with a report Wednesday from payroll services company ADP. It said small businesses hired 19,000 workers last month, the smallest amount this year. The NFIB, which lobbies on behalf of small businesses, questioned 733 of its members in the survey. A small piece of good news in the survey was a 1 percentage point increase in the number of businesses planning to hire. But only 5 percent had such plans.
