The Toronto Transit Commission filed an unfair labour practice complaint against the union after the union expelled several inspectors from membership.
During a strike, the TTC had directed the inspectors, who were excluded from the bargaining unit as managerial personnel, to perform bargaining unit work.
The union passed a resolution revoking the local membership of any inspector who complied, which resulted in the loss of their departmental seniority rights upon return to the bargaining unit.
The Board dismissed the complaint, finding that the strike provisions of the Labour Relations Act (sections 74, 76, and 78) apply only to 'employees' and not to managerial persons.
The Board further held that section 70 does not protect managerial persons seeking to enforce seniority rights under a collective agreement.
