PurposeThe aim of this research is to examine the public leadership (PL) behaviors of principals working in public schools and its effect on teacher motivation (M) and job satisfaction (JS). Moreover, the mediating role of JS in the relationship between PL and M is also explored.Design/methodology/approachThis research is quantitative and designed in relational survey model conducted with 327 teachers working in Siirt/Turkey in 2020. In the research, Public Leadership Scale, Teacher Motivation Scale and Minnesota Satisfaction Questionnaire were used. Descriptive analyses were used in data analysis. Moreover, mediating role of job satisfaction between public leadership and teacher motivation was tested.FindingsAccording to the results, the public leadership behaviors of school principals, motivation and job satisfaction of teachers are high according to teacher opinions. Additionally, public leadership behaviors of school principals have an effect on teacher motivation and job satisfaction. On the other hand, this study found a negative effect between public leadership and motivation when the effect of job satisfaction is controlled. The possible reasons for this situation were discussed in term of cultural differences.Practical implicationsThe results of this study imply that the leadership behaviors of school principals have cultural elements. Future research should be careful in measuring the political loyalty dimension of the public leadership and should take cultural element into consideration.Originality/valueAlthough there are many types of leadership, the type of leadership differs depending on the purpose of the organization, environmental conditions and culture. The lifestyle of the society, current developments and the structure of the organization are effective in interpreting the leadership needed in the organization. When looking at the models created about leadership in organizations, the effect of this type of leadership on organizational behavior is generally tried to be explained. This is also the case for motivation or job satisfaction. Therefore, this study also focuses on the effect of public leadership in explaining the job satisfaction and motivation of employees in educational organizations. However, another distinctive aspect of this research is that the cultural structure of the society is emphasized in the model to be created.
