Who are the members of the Occasional Teachers' Bargaining Unit?
Occasional Teachers are a diverse group comprised of Daily and Long-Term Occasional Teachers. We include newly licenced grads, folks who have been doing occasional work for decades, part-time permanent teachers also doing OT work, and recent retirees. For many Occasional teachers, this is a stage in their teaching careers, while for others, this is a way of life.
Regardless of the demographic make-up, these OSSTF teacher members have issues and concerns that are unique to their precarious and always changing work. Locally, the roster averages approximately 900 Occasional Teachers. Our 'full-time equivalency' is approximately 375 members.
Local services and representation for this group of OSSTF Occasional Teachers are provided by an elected Bargaining Unit executive of their peers. The areas of service include but are not limited to collective bargaining, contract maintenance, political action, and professional development.
Karen Vandewint, the Bargaining Unit President and Grievance Officer, can be contacted by telephone at 613-729-7211 ext. 209 or by e-mail: karen.vandewint@d25.osstf.ca
