The purpose of this study is to investigate what effect COVID-19 has had on the buyer-supplier relationship (BSR) in the ready-made garment (RMG) supply chain (SC) - focusing mainly on the Bangladeshi supplier point of view, but with a complementary perspective of the buyer. As the area is new and relatively unexplored, there is a gap in previous literature and research. It has not previously been studied how COVID-19 affected the relationship between buyer and supplier in the RMG SC. This study aims to narrow this gap. In this study, a qualitative research strategy was adopted, emphasizing words rather than quantification in the data collection and analysis. An inductive approach was used, starting from collecting data, where theories and literature are proposed towards the end of the research process as a result of interviews. A narrative state of the art review of literature was conducted to provide a comprehensive and unbiased review. Semi-structured in-depth interviews with Bangladeshi supplier managers were conducted over Zoom or Teams. The empirical data were coded in first-order concepts, second-order concepts, and aggregate level through the qualitative research program Nvivo. Four main second-order concepts could be identified from the interviews with the supplier side. The codes and empirical data were then analyzed through a developed analysis model based on the Conceptual Model of Social Capital. The effects that COVID-19 has had on BSR from a Bangladeshi supplier perspective are discussed and presented.
