Yes / Sharing economy is flourishing and increasingly customers are shifting towards “using instead of owning” products and services. The objective of our research is to empirically prove that low organizational trust can trigger strict organizational practices such as ethics training and audits but excessive use of both of these practices can negatively impact the relationship quality in sharing economy. In doing so, it has detrimental effects on co-creation and co-innovation particularly when the goals are related to emotional cognitive, material support and relationship building. This study, therefore, targets to scrutinize the dark side of B2B sharing economy platforms using the ethical theory of organizing. The unique contribution of this study is first, showcasing the relationships between ethical climate, ethical practices and consequences. Second, it highlights that B2B alliances that perceive strictness in ethics audits have a low level of willingness to enhance relationship quality. However, the effect of strictness in ethics training does not lead to the development of a low level of willingness to enhance relationship quality. This is an interesting finding and generates a theoretical debate. The findings of the study will promote the development of an ethical model that addresses the negative aspects of the B2B sharing economy.
