The applicant employer sought a declaration and cease and desist order against the respondent union and its officials for calling an unlawful strike.
The union had directed employees to refuse all overtime assignments, including those within statutory maximums and those covered by an Employment Standards Act permit, in support of a lawful strike at a sister corporation.
The Board found that the concerted refusal of overtime constituted an unlawful strike under the Labour Relations Act.
The Board rejected the union's argument that the Employment Standards Act conferred a right to engage in such concerted activity, holding that the ESA does not override the LRA's prohibition on unlawful strikes.
