In a Case Involving Interstate Commerce, Union Carpenters Refused to Work

Essay

In a case involving interstate commerce, union carpenters refused to work for a brewing company by which they were employed, or on construction work being done for it and for its adjoining tenant; they attempted to persuade members of other unions similarly to refuse to work; they picketed the brewer's premises, displaying signs "Unfair to Organized Labor". In this case, are the actions of the employees protected from federal prosecution?
