Intersectionality depicts the intricate interplay of various social categorizations in shaping the experiences of individuals or communities rather than single categorization alone. This article attempts to introduce intersectionality as an essential theoretical framework for research and analysis of migrant workers' lived experience with social inequalities, and at the same time, their social positionings. Initially a critique of academic feminism from a Black activist and more inclusive perspective, intersectionality has been quickly adopted by researchers from other fields as a framework due to its usefulness in researching inequalities. By tracing intersectionality back to the context where Crenshaw coined the term, together with the presentation of its key proponents and analyses of two case studies, this article hopes to shed light on the way intersectionality can be an essential tool to explore the way migrant workers employ their multiple and intersecting identities to seek upward social mobility.
