The aggravation of social class segmentation and solidification in recent years leads to the development of social class research. Moreover, due to the ubiquitous existence of social class differences within organizations, management researchers turn their attention to the vital roles of social class within organizations. However, relevant study is still scarce and scattered, which hampers the further development of social class exploration within organizations. Based on the introduction of the conception about social class in organization and its’ distinction with other related conceptions, the present study elucidates the effects of social class in organization, involving its influencing on individual attitude and behavior, on others’ cognition and evaluation, as well as imprinting the effect mechanism of childhood social class background. Then the interaction based on social class in organization and class work is discussed. Integrating the above analysis, the current research puts forward the management strategies about social class influences in view of organization and individual. At last, the future research directions of social class in organizations are proposed, which may advance the theoretical study on social class within organizations and provide implications for management practices.
