The Canadian Union of Public Employees (CUPE) filed a jurisdictional dispute application concerning the assignment of certain HVAC maintenance and repair work to the Operating Engineers rather than the Plumbers.
The Board evaluated the competing claims using established criteria, including employer preference, past practice, and the collective agreement.
The Board determined that the replacement of liquid heating valves requiring system shutdown should have been assigned to a composite crew of Plumbers and Operating Engineers.
The installation of an eye wash stand was declared Plumbers' work.
However, the shutdown and relocation of heating components was found to be properly assigned to the Operating Engineers.
