Worker rights advocates in trade unions, human rights groups, and other non-governmental organizations (NGOs) have played an increasingly important role in promoting internationally established fair labor standards as a factor in international trade.1 Particularly in the United States, recent developments have widened the scope for action on labor rights in a transnational economy. Advocates of international fair labor standards have challenged the traditional right of countries to address their labor laws and labor relations as solely internal matters. They have sought to constrain the right of multinational corporations to implement labor policies based solely upon the laws of each nation where they operate, especially where laws are designed to repress rather than protect workers,4 and provide a competitive edge in international trade.
