The applicant employer bargaining agency alleged that during a province-wide strike in the industrial, commercial and institutional (ICI) sector of the construction industry, the respondent affiliated bargaining agents continued to supply union members to certain contractors.
The Ontario Labour Relations Board found that the supply of men during a province-wide strike constituted an unlawful arrangement contrary to section 146(2) of the Labour Relations Act.
The Board also held that trade unions have an ongoing obligation under section 148(1) to take reasonable steps to ensure that a strike is called and authorized uniformly, and that the respondents breached this duty by permitting members to work.
Cease and desist orders were issued.
