Supplier diversity programs were created in the United States nearly 50 years ago to encourage private sector companies to provide business opportunities to underutilized minority business enterprises. In order to assess the experiences that minority business enterprise CEOs have with large purchasing organizations and their perceptions of justice and commitment of large purchasing organizations to the buyer–supplier relationship (BSR), this study utilizes survey data collected from 206 minority business enterprise CEOs who supply large purchasing organizations that espouse a strong commitment to supplier diversity. The theoretical framework of organizational justice is utilized to establish testable hypotheses. The results from hierarchical linear regression show minority business enterprise CEOs’ perception of large purchasing organizations’ commitment to the BSR is positively related to the distributive and informational dimensions of organizational justice. Surprisingly, the procedural dimension was found to have a significantly negative relationship. This research also found a significant, negative relationship between minority firm CEOs’ perception of distributive and informational justice and their perceptions of unethical behavior by large purchasing organizations.
