Workplace procedural justice is an important motivator for employee work attitude and performance. This research examines how procedural justice affects employee engagement. We developed three propositions. First, based on the group engagement model, we hypothesized that procedural justice enhances employee engagement through employee organizational identification. Second, employees with stronger moral identity centrality are more likely to be engaged in their jobs. Third, procedural justice compensates for the effect of moral identity centrality on employee engagement. Specifically, when procedural justice is higher, employee moral identity centrality plays a less significant role in employee engagement; whilst when procedural justice is lower, the effect of moral identity centrality on employee engagement is stronger. Research findings based on an employee survey in a leading financial service organization provide support for the above propositions.
