Signs of moderation have piled up in the labor market in recent weeks, stirring concerns about one of the brightest spots in an economy expected to slow.

The Labor Department said Tuesday the number of job openings fell by 31,000 in July to a seasonally adjusted 7.2 million, the latest sign of weakening labor demand. The results showed openings remained plentiful, but they came just days after the department reported weaker-than-expected figures for August employment.
