The importance of acquiring knowledge is to encourage creativity and innovation among employees which will not only result in changes in individuals and their behaviors, but also in organizations performance. In addition, leaders who invest in knowledge and training for their employees will have their skill level improved and raise their productivity than those who are less skilled. The study aims at evaluating the role of organizational culture between transformational leadership and human capital in the public sector in the UAE. Transformational leadership is the independent construct which is a second-order construct of idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration. The dependent construct is human capital as a second-order construct of skills, whereas collectivism represents the organizational culture as a moderating variable. This study employs structural equations modeling via PLS to analyze the 307 valid questionnaires in order to assess the proposed model. Our work has improved our insight into the importance of transformational leadership and organizational culture. Results indicated that the independent variable significantly predicted human capital, in addition to collectivism having a significant moderating role between transformational leadership and human capital. Fifty three percent of variance is proposed by the current model in case of human capital.
