3. _In order to accomplish their ends, the trade-unions seek to control their employers' business in various ways._ They demand, first, that no non-union men shall be employed even at union wages; they demand that the employer shall help them to force his employees into the unions. In this very usual demand for the "closed shop" or "union shop" the public can see very little justice. On this point, nearly always, unions forfeit in a strike the sympathy of the public; yet the unions assert that it is almost absolutely necessary to gain this point in order to carry out their objects. If a union and a non-union man work side by side there are many ways in which the employer may make the union man suffer. If business slackens, it is likely to be the union man that is discharged; if any preference is given, it is to the non-union man. Certainly all will agree that if the unions are to get the strength to enforce _all_ their demands it is essential that they make good this claim which leaves the employer almost helpless. Yet it certainly is not essential to the accomplishing of valuable services for the members of the union. The educational and mutual-benefit features are attained without this means; and much experience shows that, if their cause is strong, the organized men can carry with them a large proportion of the workers and the sympathy of the public in a contest for higher wages. It never has seemed to any considerable portion of the public any more desirable that organized labor through its officers should be able to dictate to employees, than that employers should crush the workmen. It is by just this assumption that union advocates beg the question of the "union shop." [Sidenote: Other limitations put upon industry by unions] Further, the unions direct and control the employment of labor, often limit the number of apprentices in a trade, and assume to determine who shall enjoy the privilege of learning it. They limit the output, fix the maximum amount, and forbid the use of labor-saving machinery. Whenever the unions are charged with these acts, labor leaders either deny the facts or avoid giving a direct answer, but there is no doubt that the charge is true in many ways and in many cases. The requirement that each special kind of work shall be controlled by a special trade, and disputes between rival trades, for which their jealousies are responsible, give rise to great annoyance, expense, and loss to employers and to the entire public.
