The union filed a grievance on behalf of the grievor regarding an unsuccessful application for a permanent full-time position.
The parties reached a settlement agreement in principle, which included a wage increase.
The grievor subsequently negotiated a higher wage rate directly with the employer but then refused to sign the modified Minutes of Settlement.
The employer sought to enforce the agreement with the higher wage rate.
The arbitrator found that a binding agreement was reached and directed its implementation, including the employer's subsequent commitment to the further wage increase.
