The applicants filed a complaint regarding the assignment of work involving the removal of exterior sheet metal siding for scrap at the Bruce Nuclear Power Development.
Ontario Hydro had assigned the work to the Labourers' International Union.
The Board found that Ontario Hydro's policy and past practice favoured assigning the removal of scrap material to the installing trade up to the first drop point.
The Board declared that the work should have been assigned to the Sheet Metal Workers and ordered that future similar work in the board area be assigned to them.
