I'll start, and I'll ask Martine to join in.
As you'll recall, we originally proposed that we have one route, and the unions advised us in consultations that they would like to keep the grievance route. This is a fairly clearly defined process that we've set up within the policy. It is easier to trigger a grievance, and it's something that bargaining agents are more comfortable using from time to time. That's a tool they're more used to using.
Martine.
