Conclusion
In this paper, we explore the question of why and how focal companies implement and manage social sustainability in their supply chains. Drawing from previous literature (Vereecke and Muylle, 2006; Muller and Kolk, 2010; Gimenez and Tachiawa, 2012), we combine two fundamental constructs to build our model: a focal company’s motivation to implement the social initiative (i.e. intrinsic or extrinsic) and SC engagement (i.e., information exchange or structural collaboration) to help us to understand the dynamics of social initiatives within supply chains. Through our empirical work, we identified, analyzed, and classified 34 social initiatives according to three key relationship levels in supply chains—supplier, consumer, and society (Mani et al., 2015). This research makes five contributions to research and practice. First, by analyzing the nature and scope of these social initiatives, this research suggests that integrating intrinsically motivated social sustainability initiatives in supply chains may require focal companies to adopt SC structural collaboration as a strategy, while integrating extrinsically motivated social sustainability initiatives may be achievable with information exchange only.
