Abstract
Servant leadership is a form of moral-based leadership where leaders tend to prioritize the fulfillment of the needs of followers, namely employees, customers and other stakeholders, rather than satisfying their personal needs. Although the concept is not new among both academics and practitioners, it has received growing consideration in the last decade, due to the fact that it can positively affect a series of individual and organizational outcomes, such as job satisfaction and organizational commitment. In particular, the latest trend in literature has focused on the identification of the antecedents, mediating and moderating mechanisms at the basis of this relationship, as well as on the development of a common scale to measure the construct across diverse economic and cultural contexts. The purpose of this paper is to depict the evolution of the scientific literature that has developed on the concept, to identify the main criticalities and provide avenues for future research. A dynamic methodology called "Systematic Literature Network Analysis" has been applied, combining the Systematic Literature Review approach with the analysis of bibliographic networks.
