The employer brought a preliminary motion to strike paragraphs of the union's particulars that pre-dated a 2015 grievance filed by the grievor.
The 2015 grievance, which involved family status accommodation and lost overtime, had been settled with a comprehensive release.
The arbitrator held that the settlement and release precluded the union from relying on facts relating to family status accommodation that occurred prior to the 2015 grievance.
However, particulars relating to training issues, which were not covered by the release, and events occurring after the 2015 grievance were permitted to remain.
The motion was granted in part.
