“ No court would be entitled to prevent the dissemination of the news 'This is not a Union Job,' whether it be by radio, by newspaper, by pamphlets, or by picketing. A picket carrying that sign would be proclaiming to all union men to stay away. ”

“ The line between permissible and unlawful picketing will therefore often be narrow or even tenuous. A purpose to deprive nonunion men of employment would make the picketing unlawful; a purpose to keep union men away from the job would give the picketing constitutional protection. The difficulty here is that we have no findings of fact. ”

“ If this union used the coercive power of picketing to force the contractor to discharge the nonunion men who were employed on the job, Virginia could issue the injunction. For it is within the police power of the state to keep opportunities for work open to both nonunion and union men. ”
