Marginalized stakeholders in organizations are often rendered invisible, but there is limited research on how their knowledge and experiences are made invisible, which we refer to as epistemic invisibilization, perpetuating epistemic injustice. So, we conducted a study on the lived experiences of Dalits in the Indian IT sector. Our research reveals three practices used by dominant caste groups to invisibilize the episteme of marginalized stakeholders: ignoring their knowledge, limiting their knowledge creation, and imposing dominant knowledge. In response, Dalits engage in two practices to gain epistemic visibility: producing counter-knowledge and mobilizing knowledge communities. However, their struggle for epistemic visibility remains unresolved due to the pervasive impact of historical caste-based marginalization. Our study enriches the theoretical understanding of invisibility and epistemic injustice and contributes to the emerging field of caste research within organizations.
