The research on which this dissertation is based was carried out largely in Cambridge: in the Squire Law Library, the collection of labour law materials deposited therein, and in the University Library. Part of chapter 11 draws on personal interviews with Mr. E.J. Hamley, Secretary, the Fisheries Organisation Society and Mr. N.C. Osborne , Secretary, the Firth of Forth Fishermen's Association, and I wish to record my gratitude to both these gentlemen for their assistance. I am also grateful to the Press Office of the Civil Service Department for the literature on conditions of employment in the civil service which they have supplied.
