Worker confidence in the second quarter fell in the US to a 12-month low, staffing provider Yoh and HRO Today magazine reported today in their quarterly Worker Confidence index. The index fell to a level of 99.7 from a reading of 107.6 in the first quarter.

Yoh’s index measures workers’ perceptions of four drivers of worker confidence: perceived likelihood of a job loss, a promotion, and a raise as well as overall trust in a company.

The perceived likelihood of a promotion fell by a historic amount, 21.4%, and the perceived likelihood of a raise fell back to 2016 levels; trust in company leadership also fell to its lowest level since the third quarter of 2016. The only category that saw growth was perceived likelihood of job security.

“As we’ve seen time and time again, employers cannot look only at balance sheets as the way to gauge the health of a company,” said Andy Roane, VP of recruitment process outsourcing for Yoh. “Employee confidence is a key indicator and precursor to the future success of a company, and those who make talent a priority with strategies designed to meet employee expectations will be positioned for growth over the long term.”

The survey series includes approximately 3,000 people ages 18 and up.
