Together with the ITUC and the Trade Union Advisory Committee to the OECD, ten global union federations jointly own and manage the web site Global Unions. The Global Union Federations supported the publication of a history of the movement -- Making a World of Difference: Global Unions at Work -- which was published to coincide with the launch of the ITUC in 2006. This can be downloaded from the Global Unions website. Richard Croucher and Elizabeth Cotton's Global Unions, Global Business, Middlesex University Press (2009). explains how the GUFs really work, how they are funded, analyses their current situations and discusses their relations with companies.
