The applicant, a designated employer bargaining agency, filed a complaint alleging that the respondent companies and trade unions violated the Labour Relations Act by continuing to work and supply employees during a lawful strike in the industrial, commercial and institutional (ICI) sector.
The respondents argued that pneumatic control work was governed by a separate national agreement and fell outside the provincial agreement.
The Board found that the respondent companies perform pneumatic control installation work within the ICI sector, which is a specialization of the plumbing and pipe fitting trade.
The Board declared the national agreement null and void in the ICI sector, but delayed the effect of the declaration until the expiration of the current provincial agreement to allow the parties to integrate the work.
