The aim of this study was to determine the relationship between the mobbing and motivation levels of the teachers working in primary schools. The population of the study consisted of 673 teachers working in 59 primary schools in Yakutiye district of Erzurum province in 2018-2019 academic year, and 217 teachers were the sample. Personal information form developed by the researchers, "Mobbing Scale" developed by Tanhan and Cam (2011) and "Teacher Motivation Scale" developed by Polat (2010) were used as a data collection tools. Mean, standard deviation, Pearson Product Moment Correlation Coefficient were used for statistical analysis of the data. In addition, Multiple Linear Regression Analysis was performed to determine the predictive levels of independent variables on dependent variables. As a result of the research; in terms of mobbing dimensions, the highest level was determined as the prevention of professional practices and the lowest level was determined as direct insult to the person. Taking the teacher motivation scale into consideration, it was found that the highest level was in intrinsic motivation dimension while the lowest level was in extrinsic motivation dimension. It was determined that there was a significant relationship between mobbing and motivation levels of teachers. According to the results of the regression analysis, it was found that the sub-dimensions of the mobbing significantly predicted the sub-dimensions of the teacher motivation.
