The kit has benefited from substantial contributions and support by the previous and current Regional Directors of the ILO, respectively Ng Gek Boo and Sachiko Yamamoto. Guy Thijs, Deputy Regional Director, developed the concept and guided the development of the first version and current update from start to conclusion. David Tajgman was responsible for the initial format, while Stephan Ulrich wrote extensive portions and coordinated the process towards finalization. Peter Stalker assisted with editing, rewriting, reformatting and adding illustrations to make the first version of the various booklets consistent. Karen Emmons edited both versions. Thanks are also due to Sophy Fisher, Chanitda Wiwatchanon, Johan Arvling and Kwantawan Hongladarom for their assistance and advice with the editing process, design and layout in the accompanying web site.
