I concur for the reason that the language of the act is so loose as to make it impossible for union agents, public prosecutors, those taking employment at a struck plant, or anyone else, definitely to determine who might or might not be violator or victim in instances where the question of strikebreaking arises. Upon careful analysis, the statute conceivably could be an instrument of embarrassment and oppression to union member and strikebreaker alike, if either made an erroneous interpretation of the wording of the statute.
