The applicant Labourers' union brought a jurisdictional dispute application regarding the assignment of concrete forming work on a parking garage project.
The employer had assigned the work to a composite crew of Labourers and Carpenters.
The Carpenters' union claimed exclusive jurisdiction over the work.
The Board considered various criteria, finding that area practice was inconsistent but that the employer's past practice strongly favoured the composite crew assignment.
The Board declined to hold a full hearing to hear oral evidence on employer practice, noting that jurisdictional disputes are determined by consultation based on filed briefs.
The Board confirmed the employer's assignment of the work to the composite crew.
