Currently we have what we call the work-rest rule, which is a rule that everybody has to abide by. If you're in what we consider to be a position critical to safety--train crews, locomotive conductors, RTCs, or crane operators--you have to abide by this rule. The rule sets out maximum hours of duty and mandatory periods of rest. If the rule is not respected, then we will take action.
On top of this, as I mentioned earlier, when they did their report, SCOTIC recommended that we look into fatigue. So we had a joint working group that included labour organizations, transport, and the industry. We recently published new guidelines to help people cope.
