The union and the employer reached a tentative collective agreement, which the bargaining unit members rejected in a ratification vote.
The members also refused to strike.
Relying on its constitution, the union accepted the agreement and notified the employer.
The employer refused to execute the agreement, citing the employees' rejection and concerns about the union's constitution.
The union filed an unfair labour practice complaint, and an employee subsequently filed a termination application.
The Board held that the employer breached its duty to bargain in good faith by refusing to execute the agreement, as it had no right to interfere in the union's internal ratification processes.
The Board directed the employer to execute the agreement and dismissed the termination application as untimely, reasoning that the agreement would have been in force prior to the application but for the employer's unlawful conduct.
