Social class is a complex phenomenon that impacts organizing practices at individual, group, organizational, institutional, and societal levels. In this entry, various dimensions of social class are overviewed, including social identity, type of labor, dignity, dominant discourses, communication, and social mobility. Social class is considered to be deeply rooted in social identities as well as more macrolevel manifestations, such as labor practices. As a historically pervasive manifestation, social class is globally present in material and discursive reality. Organizational communication scholars have identified ways in which social class influences our communication, dignity, and social mobility. Recent theorizing about the relationship between social class and communication points to future directions for research. Scholars have an opportunity to explore the intersection of social class with a myriad of other phenomena from an interdisciplinary perspective in order to better understand its power and function both within and outside organizational contexts.
