Worker confidence rose in the US as workers perceived the likelihoods of promotions and raises improved. Staffing provider Yoh and HRO Today magazine reported their quarterly Worker Confidence index rose to a level of 107.6 in the first quarter, the fifth straight quarter of increases and up from a reading of 104.5 in the fourth quarter.

“It should be comforting for business leaders to see that their employees are feeling confident in the workplace,” said Andy Roane, VP of recruitment process outsourcing for Yoh. “However, this sets up additional challenges for companies looking for talent during a time of relatively low unemployment. Happy, content workers are harder to recruit away from their current employer.”

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 a perceived overall trust in a company.

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