This study aims to examine the views of primary school teachers from North and South Cyprus on Teachers' Unions. Qualitative research and a comparative case study method were used for the study. Thirty-seven primary school teachers from North and South Cyprus participated in this study. The data were obtained through interviews and analyzed by the content analysis method. The comparison of the findings of the research suggests that the functions of trade unions are related to the pressing issues of education, teachers, and the nation in both regions. Turkish Cypriots placed emphasis on education-related functions, while for Greek Cypriots teachers-related functions mattered more. Turkish Cypriot teachers assessed the functions of their unions to be more unsatisfactory than their Greek Cypriot counterparts'.
