National Labor Relations Board v. International Rice Milling Co.
The Supreme Court ruled that a union did not commit an unfair labor practice when its picketers persuaded two workers on a single truck to turn back from a delivery to a mill under a recognition picket.
Because the law only bans inducing 'concerted' action by a neutral employer's workforce, and here only two individuals on one truck were affected at the picket line itself, the Court held the conduct fell outside the secondary-boycott ban and reversed a lower court ruling against the union.
“It is the object of union encouragement that is proscribed by that section, rather than the means adopted to make it felt.”
Explaining that violent picket-line conduct did not itself violate the secondary-boycott provision at issue.
How it got here: The Labor Board dismissed the union's unfair-labor-practice complaint; the Court of Appeals set aside that dismissal and sent the case back, and the Supreme Court agreed to review the dispute.
The Case in Depth
What happened
A union picketed a Louisiana rice mill to win recognition as the bargaining representative for the mill's workers, though it had not been certified to represent them. During the picketing, two employees of a trucking customer of the mill were told there was a strike and turned their truck back, though it later completed the delivery after mill management intervened. The National Labor Relations Board's regional office charged the union with an unfair labor practice.
The question before the Court
Did a union break federal labor law by getting two employees of a neutral trucking customer to turn back from delivering to a mill it was picketing?
Why it matters
The decision narrows how aggressively labor regulators can police ordinary picket-line encounters with delivery workers, giving unions more breathing room for traditional strike and recognition picketing. Employers and neutral businesses affected by picket lines get less protection under this provision when only a single truck or a handful of workers are briefly turned away.
What changes now
The Supreme Court's ruling reverses the Court of Appeals and reinstates the Labor Board's original dismissal of the complaint against the union. Because this is a final decision on the merits of this particular incident, the case does not go back for further fact-finding on this charge, though the opinion notes a related charge involving neutral railroad employees was left unresolved in a separate part of the litigation that the Board did not ask the Court to review.
What this does not decide
The Court did not decide what specific objects a union's encouragement of truly concerted conduct must target to violate the law, since it found no concerted conduct was sought here. It also did not decide whether the picket-line violence itself was unlawful, saying any such claim would need to rest on a different legal provision.

How the Court got there
The legal reasoning, step by step
- The Court focused on the statutory language making it unlawful to induce or encourage 'the employees' of a neutral employer to engage in a 'concerted' refusal to work — a requirement of collective, not merely individual, action among that employer's workforce.
- It examined the facts and found the union's conduct reached only two men on a single truck at the picket line itself, with no effort to reach other employees of the neutral customer elsewhere or more broadly.
- The Court reasoned that encouragement directed only at individual employees who happen to approach a picketed location, without any broader effort to organize collective action among a neutral employer's workforce, does not amount to inducing 'concerted' conduct.
- The Court set aside the violence that occurred on the picket line as legally beside the point for this particular charge, noting that a claim based on coercion or violence would have to rest on a different provision of the labor law, not the secondary-boycott ban at issue here.
- Relying on a separate provision protecting the right to strike unless a law specifically limits it, the Court concluded that the secondary-boycott provision does not specifically reach this kind of narrow, individual encouragement at a picket line, so no violation occurred.
