In this article, I have conceptualized union-management relations using an organizational justice framework. I consider organizational justice theory, including distributive, procedural, interactional, and what I call relational justice perspectives. Utilizing examples from my experience and research, I illustrate and discuss various forms of organizational justice operating in school systems and influencing teachers' perspectives and union actions. I urge researchers and practising educational leaders to use an organizational justice perspective to better understand teachers' perspectives and union-management relations in education.
