With regard to fatigue, it's definitely an area that we are actively working on very closely with our unions. It's not so much fatigue but the healthy rest of individuals.
When we look at safety, we're not necessarily looking at the situation that has arisen but at how to prevent the situation from occurring. When we get to fatigue, it's really about addressing proper scheduling. It's addressing healthy sleep habits. It's an education process. As well, at work, when the individual is already fatigued, we have to look prior to that, and that's what we are currently doing and we are working very closely with our unions. We are not necessarily having to wait for regulations. We are really trying to address these issues as we see there's a level of importance to doing so. We're working closely with our unions on that.
