The applicant employer brought an application under section 91 of the Labour Relations Act to resolve a jurisdictional dispute regarding the assignment of instrumentation work.
Historically, pneumatic instrumentation was assigned to the I.A.M. and electronic instrumentation to the I.B.E.W. Due to technological changes, the employer assigned pneumatic work to the I.B.E.W. to improve efficiency, which the I.A.M. grieved.
The Board found it had jurisdiction to hear the application and concluded that the existing demarcation line was irrational.
The Board ordered that jurisdiction over pneumatic instrumentation be shared on an interim basis.
