The role of fairness in multi-tier sustainable supply chains

Fairness is an important topic that forms part of an organisation's sustainability practice and agenda, particularly from a social dimension. However, past studies have rarely considered the role of fairness as a driver of sustainability in multi-tier supply chains. The purpose of this paper is twofold. First, it examines the impact of fairness perceptions on the relationship between multi-tier supply chain partners. Second, it investigates the dynamics of ongoing fairness formations in different stages of the vibrant multi-tier supply chain relationship development process. These gaps have been addressed by reporting the findings of qualitative research. Primary data were obtained from 18 procurement and supply practitioners of buying firms and their top tier-1 & 2 suppliers. Findings show that fairness perceptions have an impact on collaborative activities between multi-tier supply chain partners. These collaborative responses such as information sharing, joint relationship effort, and dedicated investment can also impact critical aspects of the multi-tier supply chain relationship such as trust, commitment, satisfaction, and conflict resolution. The findings show that multi-tier supply chain partners have different expectations but usually evaluate fairness at the review phase of the relationship development process. These considerations offer theoretical and practical guidance towards the advancement of sustainable multi-tier supply chain relationships
