The unemployment rate in Spokane County dropped to 8.2 percent in July, from 8.9 percent in June. But what looks like a sign of recovery mostly just reflects a smaller work force. The numbers of employed and unemployed both decreased last month as the labor force shrank by 2,850 workers, the state Employment Security Department reported Tuesday. The lower jobless rate mainly reflects fewer workers, not more jobs, explained Doug Tweedy, the agency’s regional labor economist in Spokane. On a positive note, private employment in July was up slightly – the first time that has happened in a long time, Tweedy said. Industries beginning to boost employment are transportation and warehousing; health services; and leisure and hospitality.
