U.S. staffing companies employed an average of 3.24 million temporary and contract workers per week in the second quarter of 2015, up 2.9% from the same period in 2014, according to data released today by the American Staffing Association. Although the April through June period marks 22 consecutive quarters of year-to-year staffing employment additions, temporary and contract job growth moderated in the second quarter.

“Staffing companies continue to create employment opportunities, even with the slowing of overall job growth,” said Richard Wahlquist, ASA president and chief executive officer. “The fact that there are currently nearly six million unfilled job openings in the U.S. is good news for job seekers, whether they are looking for employment flexibility or a permanent position.”

Temporary and contract staffing sales totaled $29.93 billion in the second quarter of 2015, 3.7% higher than in the same period last year.

On a quarter-to-quarter basis, staffing employment was up 3.5% from first quarter to second quarter, while temporary and contract staffing sales increased 6.6%.
