Although a widespread management approach, diversity management is far from being a well-defined and unambiguous one. This article outlines how this management practice emerged, and how it is enacted, and it identifies and critically discusses the two crucial areas of dissent or ambivalence within the diversity management discourse: first, the dimensionality of diversity management, and second, its legitimacy. The first issue addresses the prioritization of certain dimensions, the difficulty of clearly demarcating one dimension from another, and the unequal consideration of specific manifestations of each dimension. Taking into account the fact that everyone embodies at least one manifestation of every dimension of diversity, the aspect of intersectionality also belongs to the dimensionality of diversity. The legitimacy issue includes legitimate starting points, operating ranges, and desired outcomes of diversity management practices. The article concludes by looking toward possible future directions in diversity management research and diversity management practice.
