This review focuseson the grievance procedure research published in the past decade with specific attention on the application (or lack thereof) of social science theory to grievance research. The review concludes that the theoretical grounding of recent grievance research has improved over the earlier research, but remains quite inadequate. Recommendations on the direction that grievance research should take in the future to further improve on the theoretical content of grievance research are provided. It is argued that theory in grievance research should advance at two levels: the comprehensive systems approach, and the application of specific social science theories to narrower aspects of the grievance process.A common criticism of grievance procedure research is the lack of theoretical grounding for much of the research done prior to 1985. Several earlier reviews of the grievance literature raised the challenge of improving on the theoretical aspects of grievance research. This review focuses on the grievance procedure research published in the past decade with specific attention on the application (or lack thereof) of social science theory to grievance research. We also make recommendations on the direction that we feel grievance research should take in the future to further improve on the theoretical content of grievance research.
