As in other organizations, there is ostracism also in educational organizations. Apart from the individual consequences of being ostracized, there are also undesirable organizational consequences. Considering the potential of educational organizations to transform individuals, the effect of ostracism on teachers becomes particularly important. The purpose of the study was to examine the reasons for and results of the ostracism that teachers face at schools by the school principals, and the recommendations for solutions to prevent ostracism. The study group of the study, which was structured with the phenomenology design, consisted of 12 elementary and middle primary school teachers who had personal experience with ostracism. The data collected through interviews were analyzed with content analysis. The study revealed that teachers were exposed to ostracism for political, social and/or individual reasons. Ostracized teachers experienced psychological and organizational problems. The teachers stated that preventing ostracism in schools would be possible with a more democratic and fairer organizational culture.
