Previous studies have suggested that the extent to which employees are treated with justice at the workplace contributes to their health. We examined whether justice at work predicted incidence of deaths from cardiovascular disease.
Participants were 804 factory workers whose mortality data were collected from the Finnish national mortality register (73 deaths; mean follow-up, 25.6 years). Justice perceptions of the participants were measured using a postal survey at baseline year 1973.
Cox proportional hazards models adjusted for conventional risk factors and other psychosocial factors at work showed that employees reporting high justice at work had a 45% lower risk of cardiovascular death than their counterparts experiencing low or intermediate justice (P=.05).
Justice at work, fair decision-making procedures, and managerial skills are important factors in an effort to develop healthy and well-functioning workplaces.

Background: Justice is a fundamental value in human societies, but its effect on health is poorly described. We examined justice at work as a predictor of coronary heart disease (CHD).
Methods: Prospective occupational cohort study of 6442 male British civil servants aged 35 to 55 years without preva- lent CHD at baseline in phase 1 (1985-1988). Baseline screening included measurements of conventional risk fac- tors. Perceived justice at work and other work-related psy- chosocial factors were determined by means of question- naire at phases 1 and 2 (1989-1990). Follow-up for CHD death, first nonfatal myocardial infarction, or definite an- gina occurring from phase 2 through 1999 was based on medical records (mean follow-up, 8.7 years).
Results: Cox proportional hazard models adjusted for age and employment grade showed that employees who experienced a high level of justice at work had a lower risk of incident CHD than employees with a low or an intermediate level of justice (hazard ratio, 0.65; 95% confidence interval, 0.47-0.89). The hazard ratio did not materially change after additional adjustment for baseline cholesterol concentration, body mass index, hypertension, smoking, alcohol consumption, and physical activity. Although other psychosocial models such as job strain and effort-reward imbalance pre- dicted CHD in these data, the level of justice remained an independent predictor of incident CHD after adjustment for these factors.
Conclusion: Justice at work may have benefits for heart health among employees.

I found this study in Bob Sutton’s great book Good Boss, Bad Boss: How to Be the Best… and Learn from the Worst.
