There are disciplinary processes that we follow with respect to our unionized employees. There are a number of steps that need to be followed, managed, and so forth with those.
I would say with our management employees the tolerance level is lower. The reason for that is, and I talked a bit about it earlier, it's around the tone that you need to set, and the leadership that's expected from that group. I have not been involved in a lot of cases, but I've been involved in a couple of cases where we've released somebody because they were at a level and the behaviour was egregious enough to warrant a dismissal. I wouldn't say this is a common problem we have or a common approach we take, but that has happened.
