The Obama administration is filing a labor law complaint against Guatemala, saying treatment of workers violates CAFTA rules. The article quotes Chris Sabatini at Americas Society/Council of the America:
He said the decision to file the complaint was in part “an attempt to appease some elements of the A.F.L.-C.I.O. by demonstrating that the labor protections built into Cafta were not empty gestures.”
I agree, but I would add more for a regional context. The administration has continually expressed support (albeit tepid) for FTAs with Colombia and Panama, but treatment of labor has slowed them down to almost a halt. By taking such a measure, the administration is also sending a signal to those who oppose those FTAs that it will take labor issues seriously.
