U.S. job openings remained close to record levels in April, and workers continued to quit at an elevated rate, signs of an exceptionally tight labor market that has contributed to historically high inflation.

The Labor Department on Wednesday said there were a seasonally adjusted 11.4 million job openings in April, a decrease from an upwardly revised record high of 11.9 million openings in the prior month. The number of times workers quit their jobs fell slightly to 4.4 million.
