Conflict may occur in any organization (and hence school) and, for schools, conflict management style is a joint activity and the degree of its effectiveness determines the type of impact of conflict on school performance. This empirical study investigates the potential sources of conflict in Greek primary schools, determine appropriate approaches for the handling of conflicts and offers recommendations, based on the findings, for a more creative conflict management style in order to enhance school performance. Anonymous questionnaires were distributed to primary school educators in two Greek regions, one of which was the metropolitan area of Athens, resulting in a sample of 414 completed questionnaires. The results showed that school conflicts often arise in the school and that when school conflicts did occur they were mainly attributed to both interpersonal and organizational reasons. Moreover, the results showed that there is a greater likelihood for these conflicts to arise in urban schools than in other regions. This study supports the view that integration, collaboration and coherence are the key factors for cultivating a constructive conflict management strategy and enhancing better school performance.
