The union filed a group grievance alleging that the employer violated the collective agreement by failing to pay acting pay to Investigators (FO5) who were assigned files with a tax value exceeding $25,000, which the union claimed were duties of the higher-classified Senior Investigator (AFA20) position.
At the conclusion of the union's case, the employer brought a non-suit motion.
The Grievance Settlement Board applied the 'sufficient evidence' standard and upheld the non-suit motion, finding that the union failed to establish a prima facie case.
The Board concluded that the work performed was not outside the scope of the FO5 position and, even if it were, the grievors did not perform all the core or significant duties of the AFA20 position, such as leadership, training, and mentoring.
