The modern trade union appeared in England shortly before the industrial revolution,[2] and has extended as fast and as far as the same stage of industrial development has been attained in other countries. The effort of wage workers to organize themselves appears everywhere to result from the separation of the economic and personal interests of employers and workmen. As the control of industry became more concentrated in larger units with the advent of power machinery, the feeling of economic unity among the different ranks of industry was further weakened. The average workman had less opportunity of becoming a master, an employer. In the days of the old hand industry, master, journeyman, and apprentice worked side by side at the same bench. Almost every apprentice might hope to become some time a master, and many a one did so. To-day most wage-workers in large establishments have no hope of rising out of their positions. The mere largeness of an establishment forbids also the personal acquaintance of employer and workman. As a result of these changes, the workmen become more "class-conscious" of their position as wage-workers and the employers in many establishments take the attitude of buyers of labor as a mere ware. When the employer then feels the pressure of competition he is more likely to force the lowest wage that is possible and to compel the workers to accept less favorable conditions than if he were in more personal relations with them. Where the immediate direction of an establishment is intrusted to paid managers who are responsible to stockholders, the managers' success is judged almost exclusively by the dividends they succeed in earning. Hence they are under stronger and more persistent temptation than are active owners to drive hard bargains with their employees. Many examples might be found where managers and resident directors have wished to pursue a more liberal policy than absentee shareholders would permit.
