"The Washington, DC office of North America's Building Trades Unions (NABTU) provides essential coordination and support to the work of its affiliated national and international unions in order that, through inter-trade solidarity, organized construction workers achieve a powerful voice in government, in bargaining, and in their communities. For nearly a century, we have worked to secure the trade jurisdiction and autonomy of its affiliates as the respected arbiter of trade issues and through that work has contributed to the continuity of employment and economic security of organized construction workers in the United States and Canada."
