The Rand decision put forward the basic principle that all who benefited from a union, whether they wished to be a member or not, must pay dues. This was to be enforced by a compulsory dues check-off. He wrote in his decision:
“I consider it entirely equitable then that all employees should be required to shoulder their portion of the burden of expense for administering the law of their employment, the union contract; that they must take the burden along with the benefit.”
Justice Rand, January 29, 1946.
