WASHINGTON — U.S. job openings stayed at a surprisingly strong 7.6 million in May as the American labor market remains resilient in the face of the economic shock from the Iran war.

Forecasters had expected employers to post just 7 million openings in May.

The job market is sturdy but not exactly booming. Layoffs rose in May, and the number of people quitting their jobs — a sign of confidence in their prospects — ticked up only slightly. That’s according to data from the Bureau of Labor Statistics released Tuesday.

Employers are advertising openings, but they aren’t actually doing much hiring. Gross hiring — before counting people who lost or quit their jobs — dipped to 5.17 million in May from 5.26 million in April.
