The applicant union applied for certification to represent construction labourers employed by the respondent.
The respondent and the intervener union argued the application was untimely because they had entered into an 'all employee' collective agreement that covered the labourers.
The Board found that the intervener had only been certified to represent equipment operators and did not represent a majority of the labourers when the broader collective agreement was signed.
The Board declared under section 60 of the Labour Relations Act that the intervener was not entitled to represent the labourers, setting aside the collective agreement as it applied to them.
The Board then found the applicant had filed sufficient membership evidence and granted the application for certification.
