The Worker Confidence Index – one of the measurements covered in the third quarter’s Worker Confidence Study – decreased between the second and third quarters of 2015, from 102.3 to 97.8. This is the lowest level since the study’s inception. The decline suggests frustration about employee’s faith in their employment situation, despite the unemployment rate drop to 5.1%. There were decreases in optimism in three of the four areas examined: Job promotion potential, raise potential, and trust. The lone metric in increase was job security, which corresponds to an overall declining national unemployment rate. The decline could be a harbinger of a challenging 2015 holiday season.
