The complainant school board alleged that a mass resignation by summer school principals, vice-principals, and curriculum resource teachers constituted an unlawful strike under the Labour Relations Act, and that the teachers' union encouraged it.
The union had issued a 'pink letter' advising members not to accept summer positions due to a collective bargaining impasse.
The Board found that the resignees were employees who had already commenced preparatory duties, and their coordinated resignations to exert bargaining pressure amounted to an unlawful strike.
The Board issued a cease and desist direction against the union and its District 16 president for counselling and supporting the unlawful strike.
