The union filed a grievance alleging the employer violated the collective agreement by failing to use reasonable efforts to persuade receiving hospitals to keep transferred employees in the union's pension plan.
Six hospitals applied for third-party standing to participate in the arbitration hearing, arguing they had a significant financial interest in the outcome.
The arbitrator denied the applications for standing, finding that the hospitals' financial interest was analogous to that of a commercial contractor and did not confer a legal entitlement to participate in the hearing, as they asserted no legal claim conflicting with the union's grievance under labour law.
