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.
