Social networks are taking center stage in organizations for the ways they shape and inform workplace leadership. Hofstede's cultural dimensions and social capital provide a framework for enabling better cross-cultural discussion about leadership in general and understanding how leaders in globalized workplace settings tap onto existing cultural practices and values vis-à-vis social networks. In China, Kenya, and Lebanon, these cultural practices and values include Guanxi, Ubuntu, and Wasta, respectively. Responding to calls for more studies comparing social network and on cross-cultural leadership, this chapter seeks to examine how Guanxi, Ubuntu, and Wasta shape workplace leadership and culture in the three respective countries. It discusses leadership styles, reviews the way Guanxi, Ubuntu, and Wasta informs workplace leadership respectively and their intersections, generates a conceptual framework, offers recommendations, suggests future research possibilities, and provides implications for human resource development.
