The numbers: The number of U.S. job openings rebounded to a near-record 7.49 million in March, showing that companies are still ready and willing to hire even though the economy is not growing as rapidly as it was a year earlier.

Job openings had fallen to nine-month low of 7.14 million in February, when hiring was crimped by poor weather and the lingering effects of a partial government shutdown. Openings hit an all-time high of 7.63 million last November.

What happened: Transportation and warehousing companies — the firms that deliver internet packages — increased help-wanted ads by 87,000. Job listings for construction rose 73,000. And real estate-related job openings climbed by 57,000.

Job openings for the federal government fell by 15,000, the Labor Department said Tuesday.

The share of people who left jobs on their own, known as the quits rate, was flat at 2.5% among private-sector employees. The rate was unchanged at 2.3% for all workers including those in government.

More workers tend to quit when they feel secure enough to leave one job for another — a sign of a healthy economy. The quits rate has risen steadily in the past decade from a post-recession low of 1.4%, though it appears to have peaked.

Big picture: A strong labor market is acting as guardrails for the U.S. economy, keeping it on track to break the record for longest expansion ever in a few months. The rate of unemployment fell last month to a nearly 50-year low of 3.6% and layoffs are also at a half-century low.

The pace of hiring has slowed since last fall and job openings have come off their record highs, but there are still more jobs available than there are unemployed Americans. Some 5.8 million people were classified as unemployed in April, meaning they want to work and are actively seeking a job.

“Job openings have now exceeded the number of unemployed Americans for 13 straight months,” noted Julia Pollak, a labor economist at employment marketplace ZipRecruiter.

What they are saying? “This report is a calming return to the trend we’ve seen for years now: high labor demand translating into a slow but steady increase in worker confidence,’said Nick Bunker, an economist at Indeed Hiring Lab. “This uptick is a positive sign, though year-over-year growth in job postings is still on the decline.”

Market reaction: The Dow Jones Industrial Average DJIA, +0.50% and S&P 500 SPX, +0.60% fell sharply again in Tuesday trades, setting up a second straight loss amid a flareup in trade tensions between the Trump White House and China.
