Certainly there are collective agreements and they're subject to negotiations that come up. I think that this largely comes up, of course, because of what we saw this past summer. From the union's viewpoint, that was a self-inflicted wound by Canada Post. We were very clear, and we've been very clear for a number of years, that when we are in a labour dispute, we want to have a minimum impact in respect to the customers. We have taken extreme measures to ensure that.
If you look back a number of years ago to the last labour dispute that occurred in 2011, at that point we simply had rotating strikes, which slowed down the system but didn't stop it. For us, customer service and being able to keep that mail stream moving is paramount for the Canadian people. If you look back a number of years, that's been our history.
It hasn't been what it was, such as in 1981. That was 35 years ago. It was the last time we had a full-out postal strike. Always it's been rotating strikes, and usually it's only come to a point where there was no postal service as a result of either government intervention or Canada Post locking us out and shutting down the service.
As I said, the most recent one was a self-inflicted wound. We were very clear that we wanted to make sure the Canadian people continued to get mail even though there was a collective agreement being negotiated, and even though under the Canada Labour Code we had the right to strike.
