The union filed a grievance challenging three disciplinary suspensions given to the grievor.
The employer raised a preliminary objection that the grievance was filed beyond the time limits set out in the collective agreement.
The grievor argued she did not realize the suspensions were disciplinary and was under stress due to her mother's passing.
The Grievance Settlement Board found the grievor's explanation unreasonable, noting the disciplinary letters were clear and she had filed grievances previously.
Applying the Becker test, the Board declined to exercise its discretion to extend the time limits due to the unreasonable and lengthy delay.
The grievance was dismissed.
