WASHINGTON (AP) — U.S. employers have yet to start hiring aggressively — a concern the Federal Reserve will weigh in deciding this month whether to slow its bond buying and, if so, by how much.

Employers added 169,000 jobs in August but many fewer in June and July than previously thought, the Labor Department said Friday. Combined, June, July and August amounted to the weakest three-month stretch of job growth in a year.
