Abstract
The aim of the research is to describe and analyze teacher’s work ethic, which is affected by the charismatic leadership of school principals and teacher’s self-concept. Survey method was adopted by using casual approach as an assessment method. The research was conducted in 15 state elementary schools with a sample of 149 teachers located in Pesanggrahan sub district, south Jakarta Indonesia. The result shows that principal’s charismatic leadership has a direct and positive effect on teacher’s work ethic, teacher’s self-concept has a direct and positive effect on teacher’s work ethic, and principal’s charismatic leadership has a direct and positive effect on teacher’s self-concept. It is inferred that teacher’s work ethic will be able to be achieved optimally by increasing school principal’s charismatic leadership and teacher’s self-concept. Thus, it can be said that the improvement of self-concept and work ethic is interrelated with the capability of the school principal to perform his/her charismatic leadership.
