I'd like to try and clarify the debate by talking about the Quebec experience.
On the one hand, union organizations never maintained that the complaint process was adequate. We have struggled not to head towards negotiation, but to demand a proactive law. In Quebec, we've had both regimes. I come back to the public sector. As long as there was not a proactive law, we did what we could with negotiations. The proactive law accounted for a difference of $2 billion for women. It shows that negotiations can sometimes correct certain aspects, but it's not true that the right to pay equity is fully achieved.
On the other hand, regarding the responsibility of unions, a proactive law forces both parties to assume their responsibilities. People can submit complaints to their unions, which may refuse to act, or act in bad faith, or don't fulfil their responsibilities. But what we have now in the federal law is something else. It makes the union responsible for the payment of wages. This is a far cry from condemning a union that doesn't do its job properly, from imposing a fine on it, from compelling it comply, and getting it to think it must pay wages.
