The mediation effects of job characteristics between interpersonal justice, informational justice and job engagement

The present study examined the role of interactional justice (interpersonal and informational) on job engagement and the mediation role of job characteristics between interactional justice and job engagement (physical, cognitive and emotional). Using a sample of 252 employees from information technology firms based in South India, the current study analysed the hypothesised mediation model by employing partial least squares-structural equation modelling (PLS-SEM). Results revealed that interpersonal justice and informational justice have positive impacts on job characteristics, and job characteristics partially mediate between interactional justice and job engagement. The findings of the study emphasise that (a) interactional justice has a positive relationship with job characteristics which is scarcely found in the literature; and (b) job characteristics act as a mediator between interactional justice and job engagement, which is a new perspective. All three energies of job engagement are examined individually.
