About Us


The Ontario Secondary School Teachers’ Federation (OSSTF/FEESO) is a trade union representing almost 60,000 members in 140 bargaining units across the province.
Founded in 1919, OSSTF/FEESO represents public high school teachers, occasional teachers, educational assistants, continuing education teachers and instructors, psychologists, secretaries, speech-language pathologists, social workers, plant support personnel, attendance counsellors and many other educational workers.
OSSTF/FEESO bargaining units represent both English and French members in elementary and secondary school workplaces, private schools, consortia offering support services to school boards and universities.


The mandate of the Federation is to associate and unite teachers and all other employees of educational institutions or local government bodies of whatever nature, or who are employed by or engaged by any organization which provides services to an educational institution or to a local government body, whether directly or indirectly, within the Province of Ontario, and to promote and safeguard their interests.

  3. prior to registering a complaint of harassment or bullying against another member, inform the member, either personally or through a representative, that the actions are unwelcome and must cease;
  4. Any member making an adverse report on another member shall include in the written statement the relevant date, details and alleged incidents that were related in the adverse report to the member and address and deliver the written statement to the member. (A.96)
