At OSSTF/FEESO,  we believe that the whole school is a classroom. In one way or another,  everyone working in a school makes a real contribution to the success and  wellbeing of the kids.
This idea  came from our members that includes high school teachers, plus all categories  of support staff and professionals in public high schools and universities. It’s a unique combination and a unique vision, and  it gives us a special understanding of how to protect and enhance public education  in Ontario. 
It wasn’t  always this way. OSSTF/FEESO began in 1919 with high school, collegiate and  continuation school teachers. Up to 1944, it was voluntary, but almost all of  them joined and paid dues. 
In 1984,  occasional, summer and night school teachers joined up. The success of  organizing these groups was inspiring and soon, support staff like me were  eager to join. So in the late 80s, OSSTF/FEESO became a trade union and  expanded the vision to include all the people who make schools work.
With our  bigger membership, it was time to play a bigger role in the labour movement. We  joined the Canadian Labour Congress in 1996 and the Ontario Federation of  Labour in 2002. That same year, we welcomed new members from the university  sector.
In July 2018  OSSTF/FEESO rejoined the Canadian Teacher’s Federation as a Member  organization.  Increasing our alliances  with like-minded organizations will be crucial in the advancement of the cause  of education in a world where education policy has become increasingly  centralized and coordinated across jurisidictions.
There are  over 70,000 of us now. Diverse, strong and still growing. We are more than  teachers.
We are  educational assistants, continuing education teachers and instructors,  psychologists, secretaries, speech-language pathologists, social workers, plant  support personnel, attendance counselors and many other education  professionals. We are in all areas of public education we are focused on protecting  and enhancing public education. 
No other representative  organization has as much history, diversity, expertise, respect and or  influence in the field of public education in Ontario.
And all  sharing the vision. It’s how we do what’s right for public education in  Ontario.
