The applicant, United Brotherhood of Carpenters and Joiners of America, Local 1946, brought a jurisdictional dispute under section 99 of the Labour Relations Act, 1995, regarding the erection of a pre-engineered building.
The employer, Wheelwright Construction Inc., had assigned the work to a 50-50 composite crew of ironworkers and carpenters.
The responding party, Sheet Metal Workers' International Association, Local 473, argued the work should have been assigned to a composite crew including sheet metal workers, citing area practice.
The Board found that the four installations relied upon by the responding party did not create an overwhelming area practice sufficient to overturn the employer's assignment.
The Board upheld the assignment to the composite crew of ironworkers and carpenters.
