The aim of this study is to find out whether there is a significant relationship between perceived political discrimination and dissent behaviour displayed by primary school teachers. This study was designed with correlational research method and survey technique was used to collect data. Primary school teachers working in Tuzla, Istanbul constitute the research population of the study. 362 teachers willing to answer the scales participated in the study. The data were collected through the Political Discrimination Scale for Teachers developed by Keskinkiliç-Kara and Büyüköksüz (2013) and Dissent Behaviours Scale developed by Özdemir (2013). The results have shown that the level of discrimination in administrative issues perceived by teacher is "high" and the level of discrimination in social relations "medium". The level of political discrimination perceived by teachers does not significantly differ by gender, age, seniority or duration of employment at the institution. It has been found that there is a significant positive relationship between the administrative discrimination sub-dimension of political discrimination and the latent dissent sub-dimension of organizational dissent and that discrimination in administrative issues is a low predictor of latent dissent.
