Originally published in 1952, The Government of British Trade Unions analyses the government, in theory and in practice, of one of Britain’s most important labour organizations – The Transport and General Works Union in the first half of the 20^th Century. It is an appraisal of the role of the rank and file within this union of over one million members, to determine both the opportunity for, and the extent of their participation in, this State within a State. Original sources and materials, which had not previously been made public in relation to any major British or American Trade Union, were used to ascertain member turnover, participation in elections, attendance at Branch meetings and the effect of the repeal of the Trade Disputes Act on Labour Party membership. The study is of great interest both for the light it throws on the general question of Trade Unions in the modern State, and for its analysis of the Transport and General Works Union itself.
