My concerns can be summarized as follows. I think the labour rights should be subjected to the same enforcement mechanism that is given to investor rights. Again, whether that's in a side agreement or not, to some extent, may be beside the point. Clearly, if you have the labour rights provisions in the body of the agreement, as with U.S.-Peru, it follows that you'll likely have the same enforcement mechanism applying to all rights, at least in theory.
My concern is the following. We have this enforcement mechanism that in its broad strokes is similar to the enforcement mechanism that we have had under the labour side agreement to NAFTA. Our empirical experience has clearly been that the enforcement mechanism to labour rights under NAFTA does not work. It's that simple. It doesn't protect workers' rights.
There's no basis to conclude, therefore, in my view, that while there are improvements in these labour rights provisions, and you cited some of them yourself, the fact that it has incorporated what are commonly called ILO core labour standards into the substantive provisions of the agreement is an improvement. However, rights are only as good as what you can enforce. You can have all the terrific statements and all of the substantive rights you want, but if you can't enforce them, they won't actually do much to improve workers' rights.
