I think part of the challenge is when you allow exceptions for replacement workers. Where do you find that line with respect to what work is in the national interest, for example? What work is necessarily involved for the maintenance of critical infrastructure?
I think the best way to resolve that situation is between the affected parties. There could be some broad definitions that we have to be careful about, but you would have to look at some ways the affected parties—that is, the union—would be in agreement to have any kind of replacement workers to maintain critical infrastructure.
In our history at Canada's Building Trades Unions, we have made some exceptions when we've been on strike, but those exceptions are rare.
