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