The appellant union filed grievances on behalf of two employees (one casual, one probationary) who were dismissed.
The collective agreement denied them access to the grievance procedure for dismissals.
The union argued that the public order standard in s. 124 of the Act respecting labour standards, which prohibits dismissal without good and sufficient cause after two years of service, was implicitly incorporated into the collective agreement, giving the arbitrator jurisdiction.
The Supreme Court of Canada held that while the standard is not implicitly incorporated, the public order nature of the Act renders the collective agreement clauses denying arbitration absolutely null.
Consequently, the grievance arbitrator has jurisdiction to hear the complaints and provide a recourse equivalent to that of the Commission des relations du travail.
