The complainant filed a grievance alleging the employer unfairly declared her position abandoned under section 42 of the Public Service of Ontario Act, 2006.
The employer raised a preliminary objection that the complainant failed to file her Notice of Proposal within the mandatory 14-day time limit under O Reg 378/07.
The complainant argued the employer waived this objection by participating in mediation.
The Board held that the statutory time limits are substantive and cannot be waived.
Because the notice was filed 15 days after the complainant became aware of the decision, the Board lacked jurisdiction to hear the complaint on its merits.
The complaint was dismissed.
