In this study, descriptive and comparative in nature, I analyze teachers' dissatisfaction with their profession in Chile, Brazil, and Mexico (N = 10,846). Using data from the 2013 Teaching and Learning International Survey (TALIS), I question whether extrinsic and intrinsic elements of school organizations, in addition to teachers' personal attributes, are associated with their dissatisfaction. Using multiple logistic regression, I found that Mexico is the country where teachers have the least likelihood of being dissatisfied compared with both Chile and Brazil. In agreement with the literature, I also found that collaboration among teachers and a culture of participation in the school are key characteristics associated with less dissatisfied teachers.
