Ontario Secondary School Teachers' Federation (OSSTF)


District 11

11 Thames Valley
Let us not take thought for our separate interests, but let us help one another - OSSTF Motto
OSSTF District 11 serves the membership of four OSSTF bargaining units in the Thames Valley District School Board in south-western Ontario. Altogether, there are over 2000 active OSSTF members in District 11. Members of OSSTF are part of a well-organized union of teachers and educational workers. The provincial OSSTF is divided into Districts which correspond with the school boards, and each District is made up of bargaining units. Teachers' bargaining units are subdivided into branches or worksites which are the high schools within the District. Each level interacts with each other and with the members according to the Constitution and Bylaws of the OSSTF.

    OSSTF/FEESO statement on anti-Islamic hate crime in London, Ontario

    We grieve for the London, Ontario family who lost four family members in what police report as an unconscionable, deliberate, anti-Islamic hate crime on Sunday, June 6. Our thoughts are with their relatives, friends, colleagues and all others who are coping with the trauma caused by this devastating, senseless act of violence.

    OSSTF/FEESO joins all voices that are demanding a fulsome investigation into this hateful act and for action against Islamophobia.

    All children and residents in Ontario have a right to live, learn, and prosper in a society free from the destructive effects of hate and violence. OSSTF/FEESO calls on all members to reject and denounce the destructive effects of Islamophobia, hatred and all other forms of discrimination in our communities.

    To pledge your support and help the young survivor of this horrific tragedy, please go to https://www.launchgood.com/campaign/london_community_united_against_hate#!/
