Rail traffic controllers in downtown Edmonton who operate the network on a North American basis realize this. We have rail traffic controllers sitting in Edmonton who essentially dispatch trains across North America for CN. It's a very small union compared to other unions within the group, but that group can do so.
It's not a question of isolating the unions; it's making sure there's a balance between the negotiating parties. We treat all unions on the same basis. They're all as important, one as the other, to us when it comes to how we operate the railway. There's no one trade or skill that will allow us not to operate the railway in a way that we couldn't do so with management. So I think it's important.
