Summary

Louis Brandeis Senn v. Tile Layers Protective Union Local No 5…

Members of a union might, without special statutory authorization by a state, make known the facts of a labor dispute, for freedom of speech is guaranteed by the Federal Constitution. The state may, in the exercise of its police power, regulate the methods and means of publicity as well as the use of public streets. If the end sought by the unions is not forbidden by the Federal Constitution, the state may authorize working men to seek to attain it by combining as pickets, just as it permits capitalists and employers to combine in other ways to attain their desired economic ends.

The unions concede that Senn, so long as he conducts a nonunion shop, has the right to work with his hands and tools. He may do so, as freely as he may work his employees longer hours and at lower wages than the union rules permit. He may bid for contracts at a low figure based upon low wages and long hours. But the unions contend that, since Senn's exercise of the right to do so is harmful to the interests of their members, they may seek by legal means to induce him to agree to unionize his shop and to refrain from exercising his right to work with his own hands.

There is nothing in the Federal Constitution which forbids unions from competing with nonunion concerns for customers by means of picketing as freely as one merchant competes with another by means of advertisements in the press, by circulars, or by his window display. Each member of the unions, as well as Senn, has the right to strive to earn his living.
