Innovation is a pivotal driver of competitive advantage and overall organisational success. Despite an extensive body of literature exploring the link between organisational justice (OJ) and innovation, a comprehensive synthesis regarding whether fair treatment within the workplace fosters innovation is notably lacking. This systematic review elucidates a predominantly positive correlation between OJ and various dimensions of innovation, although in some instances suggesting a neutral relationship between the two constructs. Furthermore, the research highlights knowledge sharing as a prominent intermediary variable among scholars. The study contributes significantly by demystifying the nuances of the relationship between OJ and innovation. Second, it introduces a categorisation of OJ and innovation subconstructs and identifies emergent concepts based on cluster analysis. Third, it presents a comprehensive conceptual model linking OJ, innovation, and several variables. Finally, the study offers seven theoretical research directions aimed at deepening our understanding of this topic.
