The applicants, employees at an A&P retail store, alleged that their union breached its duty of fair representation under section 74 of the Labour Relations Act.
The union had negotiated a new collective agreement with less favourable terms to facilitate the store's conversion to a different banner, aiming to preserve jobs.
The applicants argued the union should have waited until the existing collective agreement expired and allowed the full membership to vote.
The Board dismissed the application, finding that the union faced a difficult choice to prevent a potential store closure and acted reasonably by allowing the affected store employees to vote on the proposal, which the majority accepted.
The union's conduct was not arbitrary, discriminatory, or in bad faith.
