Five work assignment complaints were brought before the Ontario Labour Relations Board regarding the handling and installation of enclosures for finned tube convectors.
The parties agreed to have the Board first determine the applicability and effect of the 1956 Interim National Agreement between the two unions.
The Board found that while the agreement applied to the work in dispute, it was not dispositive of the complaints because the Sheet Metal Workers had only recently sought to rely on it.
The Board concluded that other criteria, such as area and employer past practice, must also be considered, and directed a further hearing to determine whether the complaints should proceed en bloc or individually.
