How Do Job Insecurity and Organizational Justice Relate to Depressive Symptoms and Sleep Difficulties: A Multilevel Study on Immediate and Prolonged Effects in Swedish Workers

Drawing on stress and justice literature, we argue that perceptions of job insecurity induce feelings of low procedural justice, which has immediate and prolonged negative effects on health (depressive symptoms, sleep difficulties). Moreover, we explore whether the strength of the job insecurity-justice relationship differs between individuals as a function of their average level of job insecurity over time. Finally, we explore whether the procedural justice-health relationship differs between individuals as a function of variability in justice perceptions over time. We analyzed Swedish panel data from permanent workers over four consecutive waves (with a two-year time lag between waves) using multilevel analysis, separating within- and between-person variance. Results showed that job insecurity associated negatively with procedural justice at the same time point for all waves. Prolonged effects were less stable. We found immediate (but not prolonged) indirect effects of job insecurity on health outcomes via procedural justice. Average levels in job insecurity over time moderated the within-person job insecurity-justice relationship. However, variability in procedural justice over time did not moderate the within-person justice-health relationship. In conclusion, disentangling within- and between-person variability of job insecurity and justice perceptions contributes to the understanding of health effects.
