The applicant Carpenters' union filed a jurisdictional dispute concerning the assignment of the carpentry portion of concrete forming work on a water pollution control centre project.
The work had been assigned by the subcontractor to members of the Labourers' union.
The Carpenters argued this violated a prior 'Peace Treaty' and section 162 of the Labour Relations Act.
The Board found that the Labourers' Provincial ICI agreement validly covered construction labourers performing carpentry work, and that the employer's practice and collective agreement obligations strongly favoured the assignment to the Labourers.
The Board confirmed the employer's work assignment.
