The applicant trade union applied for certification to represent carpenters employed by the respondents in the industrial, commercial, and institutional (ICI) sector, as well as all employees in all other sectors in Board Area 16.
The interveners argued that under the Board's displacement policy, the applicant must seek to represent all employees in the existing concrete forming bargaining unit.
The Board held that the requirements of section 144(1) of the Labour Relations Act take precedence over the displacement policy, allowing the applicant to carve out its traditional craft.
However, the Board found that a unit combining carpenters in the ICI sector with all trades in other sectors was inappropriate, as it would require complex sectoral determinations.
The Board determined the appropriate unit under section 144(1) to be carpenters and carpenters' apprentices in both the ICI sector and all other sectors in Board Area 16, while allowing the application to be treated as simultaneously seeking a separate unit for other trades under section 144(3).
