The applicant employer sought declarations that the concerted refusal of its employees to work overtime during a period of layoffs constituted an illegal strike under the Labour Relations Act.
The respondent union had a long-standing bylaw, accepted by the employer in practice, prohibiting overtime work while members were laid off.
The Board found that the employees were acting in accordance with a common understanding.
However, the Board declined to decide whether the conduct met the definition of a strike, instead exercising its discretion under section 92 of the Act to refuse the requested declarations and remedies.
The Board reasoned that intervening would not serve the interests of harmonious labour relations given the parties' historical acceptance of the practice and the voluntary nature of overtime under the collective agreement.
