The number of US job openings fell to 9.9 million in February, a decrease from January’s 10.6 million, according to the Labor Department. The drop was mainly in healthcare and professional services, while vacancies for construction workers rose. Meanwhile, the number of layoffs decreased and American employees left their jobs for better pay or conditions. Experts predict hiring will slow after the strong job creation in 2021 and 2022, but employers added 504,000 jobs in January and 311,000 in February, with economists believing that another 240,000 were added last month. Christopher Rupkey, chief economist at research firm FWDBONDS LLC, believes the job market is beginning to crack, and that the drop in job openings could slow down payroll employment in the months ahead in a bid to curb inflation.
