HEARING
December 9, 2025
Decision
1In April of 2011, the parties signed a Memorandum of Agreement for the Med/Arb process within this Ministry. In that agreement it was agreed that overtime grievances would be dealt with on a regular basis at every institution. It was the stated expectation that the parties would “move forward together in a timely manner to resolve as many outstanding overtime grievances” as possible at each institution. Monthly meetings were to be scheduled for this purpose. It was hoped that these monthly overtime grievance sessions would resolve most grievances.
2It was also agreed in the Memorandum that Med-Arb sessions would be held to deal exclusively with overtime grievances from time to time. The parties would meet to attempt resolution of the outstanding grievances, and the remaining disputes would be put before this Board.
3In May of 2012 the first decision from this process was issued. As agreed by the parties, that decision was without prejudice and without reasons. Since that time a number of sessions have been held and various decisions rendered. The process has not been altered and continues to serve the parties well.
4The grievances determined herein were dealt with on December 9, 2025.
5Both parties presented facts, supporting documents and made submissions regarding the various disputes. Attached as Appendix A is the list of grievances and the disposition of this Board. Any monies that are owing to individual grievors as set out in the attached appendix are to be paid at the appropriate overtime rate less statutory deductions.
6I remain seized.
Dated at Toronto, Ontario this 16^th^ day of January 2026.
