U.S. employers posted slightly more openings in June than the previous month, resulting in more available jobs than unemployed people for the third straight month, signaling a solid economy.

The Labor Department said Tuesday that job openings barely increased, rising 3,000 to 6.66 million. That’s more than the 6.56 million people who were searching for work in June. It’s also close to April’s figure of 6.8 million, a record high. Overall hiring slipped to 5.65 million from 5.75 million, and the number of people quitting their jobs declined slightly to 3.4 million from nearly 3.5 million in May.

The figures reflect a robust job market. The unemployed typically outnumber job openings, but that reversed this spring amid strong demand from employers. Businesses are optimistic about the outlook and stepping up hiring in anticipation of solid future growth. The economy expanded at a 4.1 percent annual rate in the April-June quarter, the fastest pace in four years.
