Following the Second World Congress of the International Trade Union Confederation (ITUC) held from June 21 to 25, 2010 in Vancouver, this article examines the changes undergone by international trade unionism in recent years. The increasing power of multinational corporations, as a result of globalization, has led to a transformation in international trade unionism which has produced a reorganization of its structures and the emergence of new forms of action to ensure the protection of workers´ rights worldwide. The key argument of this article is that the evolution of the structures and practices of international trade union organizations over the last two decades has been characterized by the implementation of strategies aimed, on the one hand, at reinforcing trade union unity and, on the other hand, at targeting multinational corporations. Lastly, although the transformation of international trade unionism has given rise to important structural changes, international trade union organizations continue to face formidable challenges in their efforts to effectively contribute to the regulation of the global economy.
