This paper explores the antecedents of intra-organizational social capital from a comprehensive perspective that integrates leadership as the main antecedent. To be precise, we propose that intra-organizational social capital is a direct consequence of an organizational ethical and community context to which leadership in the servant dimension plays a transcendental role. Indeed, since the seminal work of Greenleaf (1977) the servant leadership concept has been widespread among business academics and professionals for the value it brings to the organization not only in ethical but also in excellence terms. Among the recent styles and theories on leadership up to date, servant leadership fits perfectly an organizational ethical context both at the organizational or group level, acting in addition as a main promoter of that context. Furthermore, servant leadership is linked to the cultivation of helpful, altruistic and servant attitudes among the employees which are useful elements in the generation of social capital inside the organization. A model then for understanding the causes of intra-organizational socialcapital with a focus on servant leadership is here elaborated from which conclusions and implications for Management will be delineated
