Canada Post Corporation appealed an arbitrator's decision that reinstated Christopher Seivright, a temporary postal worker, after his dismissal for failing to demonstrate reasonable availability in accepting work assignments.
The arbitrator rejected Canada Post's use of a peer average acceptance rate (37.8% versus 49.9% peer average) as the sole basis for termination, finding it arbitrary and unreasonable.
The arbitrator considered contextual factors including the 24/7 operation of the York Distribution Centre, high parcel volume, the grievor's seniority, and the actual number of shifts worked (57 shifts, placing him in the top 25-30% of temporary employees).
The Divisional Court upheld the arbitrator's decision as reasonable despite departing from prior arbitral jurisprudence on certain points.
The Court of Appeal dismissed the appeal, finding no binding arbitral precedent for mechanical application of acceptance rate standards and confirming that reasonable availability must be assessed on a case-by-case basis considering relevant workplace circumstances.
