It was the dramatic events of 1852 which made the establishment of the Amalgamated Society of Engineers a turning-point in the history of the Trade Union Movement. The complete victory gained by the employers did not, as they had hoped, destroy the Engineers’ Union. The membership of the society was, in fact, never seriously shaken.[358] On the other hand, the publicity which it gained in the conflict gave it a position of unrivalled prominence in the Trade Union world. From 1852 to 1889 the elaborate constitution of the Amalgamated Society of Engineers served as the model for all new national trade societies, whilst old organisations found themselves gradually incorporating its leading features. The place occupied in 1830-34 by the cotton-spinners and the builders was, in fact, now taken by the iron trades. The “New Model” thus introduced differed, both for good and evil, from the typical Trade Unionism of the preceding generation. The engineering societies had to some extent inherited the exclusive policy of the organisations of the skilled handicraftsmen of the beginning of the century. Unlike the General Trades Unions of 1830-34 they restricted their membership to legally apprenticed workmen. Their records bear traces of the old idea of the legal incorporation of separate trades, rather than of any general union of “the productive classes.” The generous but impracticable “universalism” of the Owenite and Chartist organisations was replaced by the principle of the protection of the vested interests of the craftsman in his occupation. The preface to the rules of the parent society expresses this dominant idea by a forcible analogy: “The youth who has the good fortune and inclination for preparing himself as a useful member of society by the study of physic, and who studies that profession with success so as to obtain his diploma from the Surgeons’ Hall or College of Surgeons, naturally expects, in some measure, that he is entitled to privileges to which the pretending quack can lay no claim; and if in the practice of that useful profession he finds himself injured by such a pretender, he has the power of instituting a course of law against him. Such are the benefits connected with the learned professions. But the mechanic, though he may expend nearly an equal fortune and sacrifice an equal proportion of his life in becoming acquainted with the different branches of useful mechanism, has no law to protect his privileges.”[359] He is therefore urged to join the society, which aims at securing the same protection of his trade against interlopers as is enjoyed by the learned professions.
