You said, in your remarks and in your responses, that the bill allows for exceptions where people can be brought in to work, for example in the event of a threat to human life, a threat to public health and safety, or a risk of a catastrophic environmental impact. I think that we all agree that these exceptions are perfectly reasonable.
However, I'm wary of concepts such as national interest or national economic interest. These concepts are sometimes a bit vague and can become a catch‑all for anything to restrict workers' rights.
