The current case study examines secondary school principals’ social justice leadership (SJL) based on teachers’ perceptions. In the study, a qualitative research approach with a phenomenological design was used to explore the teachers’ perceptions regarding their principals’ SJL at Turkish secondary schools. The data were reached through semi-structured interviews. 11 participant teachers were determined as participants of the study with the maximum sampling method. The collected data were analyzed with content analysis, and three themes were reached: limited social justice, inclusive perspectives, and holistic leaders. Based on the results, teachers think that principals have a limited SJL and inclusion enactment. The participant teachers think that SJL should have a holistic perspective, including parents and teachers while ensuring social justice at school.

This study aims to investigate the views of active primary and secondary education teachers in Greece while implementing educational administration in the modern Greek school for issues related to multiculturalism and their intention to take an active role in co-shaping internal education policy, considering the country's centralized educational system and the flexibility it leaves for the participants in everyday educational reality. 1052 Primary and Secondary education teachers from Greece took part in the research. Descriptive statistics were used, followed by a test of the effect of the sample's social profile on their perceptions, and complex statistical analyzes such as correlations and multiple regression. The findings shape an educational leader who embraces the core principles of intercultural education. According to teachers, these findings are also considered encouraging, since they delineate a teacher who no longer rests, only, in their pedagogical duties, but understands that they must be part of the educational life. Finally, the findings confirmed the influence that an educational leader can exert with their behavior on the teachers at their school. This research sets the basis for the delineation of educational administration in the modern Greek multicultural educational reality by utilizing various statistical methods.
