The applicant union referred a construction industry grievance to the Board alleging the employer violated the collective agreement by failing to assign work to a composite crew of Ironworkers and Millwrights.
The employer and the intervening Millwrights argued the grievance was inarbitrable as it raised a jurisdictional dispute.
The Board held that while the grievance alleged a collective agreement violation, the underlying issue was a jurisdictional dispute over a work assignment.
The Board adjourned the grievance sine die pending the filing and disposition of a jurisdictional dispute complaint under section 93 of the Labour Relations Act.
