U.S. hiring activity exploded in March, as employers added 916,000 new jobs, mostly in leisure and hospitality, according to the latest employment report from the Bureau of Labor Statistics. Economists expected the spike, as the economy reopened more broadly, and the rate of vaccinations increased. The unemployment rate ticked down to 6 percent from 6.2 percent in February and is expected to continue falling in the coming months as more service-sector jobs return.
