Injustice at work affects work ability and role functioning: findings of a cohort study.

OBJECTIVES

The aim was to analyze the longitudinal effects of organizational injustice (OIJ) and effort-reward imbalance (ERI) on work ability, emotional role functioning and physical role functioning.

METHODS

Longitudinal data with a two-year follow-up of people previously receiving sickness absence benefits were used for analyses. OIJ and ERI were included separately and mutually in logistic regression models. Effects were tested for additivity. All analyses were additionally performed stratified by sex. All models were adjusted for sociodemographics and neuroticism.

RESULTS

1886 participants (44.5% men, mean age: 48 years) were included. When mutually adjusted, OIJ and ERI affected work ability, and OIJ affected emotional role functioning. In stratified analyses, OIJ affected all outcomes in women, and ERI affected work ability in men. Additive effects of OIJ and ERI were not identified.

CONCLUSIONS

OIJ and ERI are important risk factors of limited participation. People with experiences of health-related and work-related impairments are in need of reliable structures and just working conditions.
