Ontario Secondary School Teachers' Federation (OSSTF/FEESO)

The Ontario Secondary School Teachers' Federation (OSSTF/FEESO) is a union representing approximately 60,000 secondary school teachers and education workers in the province of Ontario. We represent secondary school teachers working in Ontario's English public schools, as well as education workers in all four major school board organizations. In addition, we represent education workers in select Universities and Independent Schools in the province.

OSSTF/FEESO is a strong, independent, socially active union that promotes and advances the cause of public education and the rights of students, educators and educational workers. While establishing working conditions for its members, OSSTF/FEESO also works to build strong public services, preserve academic freedom, prevent the privatization and commercialization of our educational institutions, ensure that students receive an education free of bias and discrimination, and provide an equitable opportunity for all students to succeed in a strong, well-funded public education system.
