Whether the Fourteenth Amendment permits Kansas to criminally punish an employer for requiring an at-will employee, as a condition of continued employment, to agree not to join or remain in a labor union.
Holding
No. As construed and applied, the Kansas statute violated the Due Process Clause because it arbitrarily interfered with the employer’s liberty of contract.
Reasoning
The Court treated the state court’s construction as decisive: Coppage was punished not for actual coercion, fraud, duress, or other unlawful pressure, but simply for insisting that Hedges choose between continued at-will employment and union membership. Hedges was an adult, competent to choose, and free to reject the proposed condition by leaving the job.
Adair v. United States controlled in principle. Adair had held that Congress could not punish an employer for discharging an employee because of union membership, because the employer and employee possessed equal rights to end an at-will employment relationship. The Court saw no meaningful constitutional difference between discharging a union member and candidly making nonmembership a condition of beginning or continuing the employment relationship.
The majority treated freedom of contract as an aspect of protected liberty and property. In its view, an employee’s right to sell labor on chosen terms corresponded to an employer’s right to decide the conditions on which to purchase it. Because either party could terminate an at-will relationship, either also could insist in advance on terms that would otherwise justify ending it.
The Court rejected the argument that the statute merely protected the employee’s freedom to join a union. A worker remained free to join a union, but did not have a constitutional right both to join one and to retain employment with an employer unwilling to employ union members. Likewise, a union itself could set membership conditions; the Court reasoned that employers could not be subjected to a more restrictive rule of contractual freedom.
