The aim of this study is to investigate the relationship between organizational dissent and life satisfaction perceptions of public primary school teachers. This research is a descriptive study in relational survey model. The sample consists of randomly chosen 200 primary school teachers who are working in Diyarbakir city center during the 2013-2014 academic year. "Organizational Dissent Scale" which is developed by Kassing (2000) and adapted from English to Turkish by Dagli (2015) and "Life Satisfaction Scale" developed by Diener, Emmons, Larsen and Griffin (1985) and adapted from English to Turkish by Dagli and Baysal (2016) were used for collecting data. As for the results of the research, it is found that according to the gender there is significant difference in the dimension of "upward dissent" and for the union membership, monthly income significant difference was found in "lateral dissent" dimension among the perceptions of teachers. Another finding of the study is that teachers are dissenting "highly" in "upward" and "lateral" dissent dimensions and there is a significant, low, negative relationship between teachers' dissent and life satisfaction perceptions [r = -0.181 (p = 0.010)].
