Private sector employment increased by 253,000 jobs from April to May according to the May ADP National Employment Report.

"May proved to be a very strong month for job growth," said Ahu Yildirmaz, vice president and co-head of the ADP Research Institute. "Professional and business services had the strongest monthly increase since 2014. This may be an indicator of broader strength in the workforce since these services are relied on by many industries." Mark Zandi, chief economist of Moody's Analytics said, "Job growth is rip-roaring. The current pace of job growth is nearly three times the rate necessary to absorb growth in the labor force. Increasingly, businesses' number one challenge will be a shortage of labor."
