On September 18, 2014, the Office of the U.S. Trade Representative (USTR) asked an arbitration panel to proceed with litigation against Guatemala under the labor enforcement provisions of the U.S.-Dominican Republic-Central America Free Trade Agreement (CAFTA-DR). The dispute, which is the first labor dispute that the United States has ever brought under a trade agreement, was initiated by six Guatemalan trade unions and the AFL-CIO in 2008 and involves Guatemala's enforcement of labor laws designed to protect workers' rights. USTR initially convened the panel in 2011, then halted its work to pursue a solution with Guatemala, which resulted in an 18-point plan that was signed in April 2013. The United States ultimately found Guatemala's compliance with its commitments under this plan to be unsatisfactory. In the coming months, the United States and Guatemala will submit briefs to the panel, which is expected to hold a hearing in 2015.
