From what we've seen, the rapid response mechanism has been effective in a number of cases where independent unions have been in recognition fights, basically, with yellow unions, as they're called—unions that are corrupt and not really representative of workers. This is often the case in the automotive industry, where these kinds of recognition fights have been going on.
It's very important for the trade agreement to support labour rights rather than help drive them down. From what I've heard from unions doing cross-border work with Mexican auto workers, it's been a help and has been effective. I would be delighted to see it expanded to other sectors of the economy.
