Prediction level of school principals' charismatic leadership behaviours on organizational silence at schools according to teacher perceptions

The aim of this study is to determine the prediction level of school principlals' charismatic leadership behaviours on organizational silence types at schools. The research is conducted in 2012-2013 educational year by the participation of high school teachers in Isparta. In the study, stratified sampling method and relational sampling model are used. Leadership behaviors of school managers have been obtained by "Leadership Behavior Inventory" and silence level of high schools are obtained by "Organizational Silence Scale". SPSS 22 program is used to analayze the data and t-test, one way ANOVA, LSD (Least Significant Difference) test as complementary post-hoc analysis to determine the differences after ANOVA test, Pearson correlation and regression analysis are conducted. The research examines regression level of dimensions of charismatic leadership "model the way", "inspire a shared vision", "challange the process", "enable others to act" and "encourage the heart" on acquiescent, defensive and pro social silence as three types of organizational silence. In the study aiming to create awareness about the effect of leadership behaviours in schools on silence and the possible negative consequences of organizational silence, teachers' opinions are investigated according to the variables such as branch of the teacher, the tenure of teacher at the school where s/he works at that time, the total tenure of the teacher, age, sex, school type and educational background. Unlike literature research and other types of leadership, there is no definite and unanimous decision to "reduce" or "increase" the effect of dimensions of charismatic leadership's on organizational silence. As a result of the research, it is determined that the teachers viewed the school principals as charismatic leaders and showed the organizational silence behavior mostly to protect their colleagues and the institution. Also it is found that "model the way" dimension of charismatic leadership reduces the acquiescent silence; "inspire a shared vision" dimension of charismatic leadership increases the acquiescent silence. Besides "enable others to act" dimension reduces defensive silence but increases pro social silence.
