United Steelworkers v. Enterprise Wheel & Car Corp.
The Supreme Court ruled that a federal appeals court was wrong to strip an arbitrator's award of reinstatement and back pay simply because the labor contract had expired before the award issued, since the arbitrator's decision was plausibly grounded in the contract itself.
The ruling reinforces that courts must enforce labor arbitration awards without second-guessing how the arbitrator read the contract, so long as the award can be traced back to the agreement — a rule that has since shaped how courts handle virtually all labor arbitration disputes.
“an arbitrator is confined to interpretation and application of the collective bargaining agreement; he does not sit to dispense his own brand of industrial justice.”
Explains the limit on an arbitrator's authority under a labor contract.
How it got here: A district court ordered arbitration and later enforced the award; the Fourth Circuit refused to enforce the reinstatement and post-expiration back-pay portions, and the union sought Supreme Court review.
The Case in Depth
What happened
A steelworkers union and a manufacturing company had a labor contract requiring arbitration of disputes and promising reinstatement and back pay for employees wrongly suspended or fired. After a group of workers walked off the job protesting a coworker's firing, the company told them they no longer had jobs. An arbitrator later found their discharge unjustified and ordered reinstatement with back pay, but by then the labor contract had expired.
The question before the Court
If a labor contract's arbitrator orders a fired worker reinstated with back pay, can a court refuse to enforce that award just because the contract had expired by the time of the ruling?
Why it matters
Unions and employers who agree to arbitrate workplace disputes can rely on arbitrators' decisions sticking, even when courts might have read the contract differently. This makes arbitration a genuinely final process rather than just a preliminary step before a lawsuit, encouraging companies and unions to keep resolving disputes through arbitration instead of the courts.
What changes now
The case goes back to the district court, which must have the arbitration completed to pin down the exact dollar amount of back pay owed after deductions. Apart from that narrow recalculation, the district court's original order enforcing reinstatement and back pay stands. This is a final merits ruling, not a temporary order, and it became one of three companion decisions setting the enduring standard for how courts review labor arbitration awards.
What this does not decide
The Court did not decide that arbitrators can never exceed their authority — it left open that an award resting purely on the arbitrator's own view of outside law, rather than the contract, would be unenforceable. It also did not resolve the exact back-pay amount, sending that calculation back for further arbitration.
Concurrences and dissents
Concurrence — Justice Frankfurter
Justice Frankfurter concurred only in the result, without elaborating his reasoning in this opinion; his fuller views on the standard for reviewing labor arbitration awards were expressed in a separate opinion in the companion case decided the same day.
Dissent — Justice Whittaker
“After the agreement expired, the employment status of these 11 employees was terminable at the will of the employer”The dissent's core reason for rejecting reinstatement and back pay after contract expiration.
Justice Whittaker agreed the discharges were arbitrable and that back pay through the contract's expiration was proper, but argued the arbitrator had no power to order reinstatement or back pay for any period after the contract expired, since no contractual rights survived its termination. He would have affirmed the Court of Appeals' modified judgment in full, treating the employees as terminable at will once the contract lapsed.
How the Court got there
The legal reasoning, step by step
- The Court explained that when parties agree to arbitrate under a labor contract, judges must not review the merits of the arbitrator's decision, because doing so would undercut the whole point of choosing arbitration to settle workplace disputes quickly and finally.
- An arbitrator's job is to interpret and apply the contract using informed judgment about workplace practices, but the arbitrator cannot simply impose his own sense of fairness — his award is valid only if it can be traced back to, or 'draws its essence from,' the collective bargaining agreement.
- The Court found the arbitrator's explanation ambiguous: he might have relied on outside law (which would exceed his authority) or on his own reading of the contract (which would be within it), but noted that arbitrators are not required to write opinions free of ambiguity, since demanding that could just lead them to stop explaining their awards altogether.
- Because there was no clear sign the arbitrator exceeded what the parties asked him to decide, and the appeals court's real objection was simply that it read the contract differently, the Court held that disagreement with an arbitrator's contract interpretation is not a valid reason to refuse enforcement.
- Applying this standard, the Court concluded the reinstatement and back-pay award should stand, since a contract could validly promise back pay up to the date of reinstatement even after the contract's stated term ended.
