I'd remind you again of the importance of maintaining balance. If you put a ban on the use of replacement workers you are giving power to the union movement. In this sense, the balance is disrupted because you're giving one group an incredible amount of power to pressure the other. And such pressure is all the more far-reaching when the conflict is nation-wide.
If Canada's banks stopped operating, if the stock market or the airline industry ground to a halt, what sort of impact do you think this would have on Canada's economy? The whole country would be paralyzed. That's why using replacement workers is important, with the proviso, of course, that unions' representational capacity isn't undermined. The proof is in the pudding: 19 complaints have been filed with the Canada Industrial Relations Board. Of these 19 complaints, 13 were deemed unsubstantiated, two were withdrawn and two remain under consideration.
So, the system works. That's why you need to be careful. Be extremely careful.
