Although there have been several attempts to address the conceptual ambiguities in the literature discussing organizational climate, organizational culture, and their interrelationship, there remains much confusion and a general lack of clarity about what these two constructs represent, as well as how they may interrelate. In order to provide some clarity, we provide a comprehensive review of both constructs and conclude with a model describing how organizational climate can be viewed as a bottom-up (i.e., flowing from employee perceptions) indicator of the underlying core values and assumptions that form the organization's culture. Recommendations for researchers seeking to investigate organizational climate and culture, as well as suggestions for future research, are discussed throughout the chapter.
