WASHINGTON (AP) -- U.S. employers advertised more jobs in May than April, a hopeful sign after three months of weak hiring.
Job openings rose to a seasonally adjusted 3.6 million, the Labor Department said Tuesday. That's up from 3.4 million in April. It's also the second-highest level in nearly four years, just behind March's 3.7 million.
