Finally, we must guard against a further misconception. Neither labour-boards nor labour-chambers must be confounded with those voluntary representative class organisations, and joint committees in which both classes meet together for Labour Protection, and for objects quite outside the sphere of Labour Protection. The labour-boards indicated would be special organs of a public nature, regulated by the State; labour-chambers would also be organs recognised and regulated by the State, working in consultation with the labour-boards, and exercising control over the labour-boards. The voluntary organs of association, on the other hand, with their secretaries and joint committees, are free representative, executive, and arbitrative organs of both classes. A distinction must be drawn between the public and voluntary organs. It is of course not impossible in all cases that the free "labour-chambers," in their ordinary and special meetings might exercise extraordinary powers, besides acting as regular and general organs of conciliation and arbitration. The Unions and other trade organisations of to-day can in their present form hardly be regarded as the last word in the history of labour organisation. In the second chapter we had to guard against the error of looking on Labour Protection merely as factory protection, and protection of women and juvenile workers; we must with equal insistence draw attention to the fact that Labour Protection is not confined in its scope to protection of employment, or in its organisation to the machinery of industrial inspection. This will be shown in Chapters IV. to VIII. The foregoing survey of the existing conditions and tendencies of Labour Protection makes it clear that Labour Protection in scope, legislative methods, and organisation, is only a means of supplementing and supporting in a special manner the already long established forms of State protection of labour (in the widest sense), and the still older forms of non-governmental Labour Protection (in its widest sense) the necessity for which arises from the special modern developments of industry.
