WASHINGTON (AP) — A private survey shows U.S. businesses last month added the most jobs in a year, powered by big gains in manufacturing and construction. Payroll processor ADP says companies and small businesses added 215,000 jobs in November. And ADP says private employers added 184,000 jobs in October, much stronger than its initial estimate of 130,000. The ADP numbers cover only private businesses and often diverge from the government's more comprehensive report. Last month, the Labor Department said private businesses added 212,000 jobs in October. The Labor Department will report on November job growth Friday.
