The complainants, who were laid off, alleged that the respondent union breached its duty of fair representation under section 68 of the Labour Relations Act by refusing to process their grievances to arbitration.
The union's grievance committee had determined that the grievances lacked merit because the employer's initial failure to post the positions violated the collective agreement, and processing the grievances would undermine the seniority provisions.
Despite a general membership vote supporting the grievances, the committee, after consulting with a union staff representative, maintained its refusal.
The Board dismissed the complaint, finding that the union directed its mind to relevant labour relations considerations and did not act arbitrarily, discriminatorily, or in bad faith.
