The organizational sciences are not immune to our culture’s burgeoning interest in religion and spirituality, and such interest is taxing the capacity of scholars to keep pace both theoretically and methodologically. Drawing upon the expertise of psychologists of religion and spirituality is crucial to the development of the science of workplace spirituality. This paper explores promising topical areas for theoretical development and empirical research in workplace spirituality, including further defining and conceptualizing workplace spirituality, the role of the psychology of religion, levels of analysis, and other critical issues for advancing the science of workplace spirituality.
