# Is happiness for all? The happiness halo effect on coworkers’ perceptions

## TL;DR

Happy employees are seen more positively by coworkers, but this effect depends on the observer's own happiness.

## Contribution

This study identifies a happiness halo effect in peer perceptions and shows how personal happiness mediates these evaluations.

## Key findings

- Employees' happiness predicts their positive perceptions of happy colleagues' performance.
- Affective attitudes and trust mediate the relationship between happiness and performance evaluations.
- Unhappy employees may perceive happy colleagues less favorably.

## Abstract

The halo effect is a cognitive bias, in which a specific attribute of an individual influences their overall evaluation. The “halo effect of happiness” refers to a situation in which happier individuals receive a more positive global evaluation. While previous research assessed perceptions of happy employees by supervisors, this study examines how happy colleagues are perceived by their peers. We hypothesize that employees’ happiness would positively predict their perceptions of happy colleagues’ performance, and that affective attitudes and trust would mediate this relationship.

A sample of 863 employees in the United States completed an online survey assessing their perceptions of happy colleagues’ job performance, affective attitudes and trust, and various measures of happiness.

The findings indicate that there is a happiness halo effect in perceptions of happy colleagues’ performance and reveal that employees’ own happiness predicts these perceptions through their affective attitudes and trust in happy colleagues.

Overall, this study highlights that while their colleagues generally perceive happy employees positively, unhappy colleagues may perceive them less favorably. Organizations should consider the diverse needs of all employees to enhance overall wellbeing.
