In the past, labour unions have suggested that right-to-work legislation is actually a subsidy to corporations and that it's an unfair subsidy. Under NAFTA or under the WTO, we could possibly launch a complaint regarding how the United States unfairly subsidizes companies by allowing them to pay workers less, because that's what ends up happening in right-to-work states. It's also a violation of the ILO conventions around the right to organize, and freedom of association, and all of those things.
That could be something we could raise as an offensive ask and say, “Look, if you can't ratify 98 or improve the labour chapter, this is what we're going to have to do.” Trump and Obama both talked about improving the labour chapter, but didn't do it because they are as much in violation as Mexico is.
