This paper offers an ethnomethodological membership categorization analysis (MCA) of an episode of argumentative talk in a bank, between a recent Indian migrant and her white British area manager. MCA examines how members use categorizations in the course of their everyday practical activities including workplace meetings. Our analysis shows how the "interactional trouble" between an employee and manager leads to the manager racially Othering the employee by invoking attributes resonant with what researchers call coloniality. Although theories of everyday racism and microaggression focus on everyday interactions, attention is not usually given to the moment-by-moment, turn-by-turn interactions and racial categorizations. In contrast, the MCA of our case study enables us to explicate the complexities of racializing and re-colonizing work in specific organizational encounters. Racist interactions in organizations are complex, contestable, and draw on various shared categories, resources, and knowledges deployed to achieve situated institutional aims. In our in-depth, close analysis of a relatively short interaction, we are able to reveal the institutional, gendered, racial, and colonial categories, and institutional and colonial devices that were made relevant; enabling us to explicate how racism works in the organizational every day. Studies of racist interactions stress there are specificities to the categories mobilized in organizational settings for
