While the term “workforce diversity” is commonly used in scholarly articles as well as in the popular press, the focus and scope of the research is both varied and broad. Until recently, most studies have focused on a single dimension of diversity (e.g., age, sex, race) in a domestic, typically U.S. context. In a world of globalization populated by boundaryless and virtual organizations, it is time to revisit the old theories of diversity and to create a new set of paradigms. Therefore, in this article we examine multiple dimensions of diversity to assess the current status of the literature, and to make some suggestions going forward.
