March 2024 - Member Update


The Occasional Teachers Bargaining Unit has ratified the local tentative 2022-2026 Collective Agreement. The OCDSB will be voting on the same agreement at an upcoming meeting (scheduled for March 26th). Once both sides have ratified, we will move forward with posting the new local contract language.

Mediation dates continue centrally on salary issues and centrally bargained language. Arbitration is set for mid-April with an arbitration decision expected before the end of this school year.  The terms of Central and Local Agreements will come into effect upon the finalization of VBIA.

Who are the Occasional Teachers' Bargaining Unit?

Occasional Teachers are a diverse group comprised of career Occasional Teachers, Short-Term and Long-Term Occasional Teachers and an ever increasing retired teacher population. 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 members representing approximately 6,000 individuals have issues and concerns that are often unique to their circumstance. Locally, the roster for this group of OSSTF teaching professionals averages more than 750 Occasional Teachers.

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, communications, and professional development.

Susan Rab, the Bargaining Unit President and Grievance Officer, can be contacted by telephone at 613-729-7211 ext. 209 or by e-mail: susan.rab@d25.osstf.ca
