The complainant trade union alleged that the respondent security company, acting on behalf of the struck employer, committed unfair labour practices by planting an undercover investigator within the bargaining unit during a lengthy strike.
The investigator posed as a striking employee, reported to the employer on union bargaining strategy and internal dissension, fostered dissent among the strikers, and engaged in unlawful acts on the picket line.
The Ontario Labour Relations Board found that the respondent's actions constituted a flagrant violation of section 64 of the Labour Relations Act by interfering with the administration of the trade union and the representation of employees.
The Board held that infiltrating a trade union during or in anticipation of a strike is a per se violation of the Act.
The Board ordered the respondent to compensate the union for half of the wages and strike pay lost due to the five-week prolongation of the strike caused by its actions, and to provide written notice of its violation to any trade union it is retained to act against in the future.
