Thank you for your question, Mr. Boulerice.
I would say we don't yet know the long-term effects of prolonged exposure to this toxic sound. You have to understand that we come and work day after day and that we are currently on the platform three or four hours every day. Before the pandemic hit, we were working six hours a day. Then the Translation Bureau adopted the precautionary principle and shortened our workload to four hours. However, we're still getting injured even at four hours a day.
Now the bureau wants to increase our workload to five hours a day. We think that's dangerous. All that to say that we don't exactly know how these injuries affect the inner ear, but we do know something is happening. The studies are under way, and the empirical evidence of the injuries we are incurring is being gathered.
