Abstract

In order to test the social mechanisms by which climate emerges, this study introduces a model that combines transformational leadership managerial consistency and social interaction as antecedents of climate strength (the degree of within-unit agreement of climate perceptions). The climate literature shows limited empirical research in the area of climate antecedents. In this study we tested a number of hypotheses regarding climate antecedents using safety climate as an exemplar. The sample consisted of 45 platoons of infantry soldiers from five different military camps. Results indicate that there exists a partially mediated model between transformational leadership and climate strength with density of group communication as a mediating variable. In addition, the results showed that managerial consistency has an independent effect on climate strength. Managerial consistency was also found to be a moderator in the relation between close-friendship density and climate strength, such that the lower the consistency, the higher the effect of density on climate strength.

An independent and direct effect was found between group centralization of communication and friendship networks. This relationship exerted additive effects on climate strength over transformational leadership. Furthermore, whereas centralization of the communication network was found to be negatively related to climate strength, centralization of the friendship network was found to be positively related to climate strength. Theoretical, empirical and practical implications are discussed.
