If I may add to it, you mentioned that the employer could decide it's not dangerous. With the change to the internal responsibility system, it's important to note that the health and safety committee, both the employer and the unions' employee representatives, will actually have a stronger role in ensuring that the dangers and hazards are being looked at, both throughout the entire workplace processes, if you will, as well as if there's a refusal process. It's not left to an employer to decide that this is dangerous or that's dangerous.
