Lora Lingle worked for the Norge Division of Magic Chef, Inc. in Illinois and was a member of a union whose collective bargaining agreement (CBA) included a just-cause discharge standard and a grievance-arbitration procedure. After Lingle reported a work-related injury and filed a workers' compensation claim, the employer discharged her, asserting that she had filed a false claim or otherwise engaged in misconduct. Lingle filed a grievance under the CBA and separately brought a state-law tort claim in Illinois court for retaliatory discharge, alleging she was fired for exercising her right to seek workers' compensation benefits, a cause of action recognized under Illinois law. The employer removed the case to federal court, invoking the doctrine of complete preemption under LMRA §301 and arguing that the retaliatory discharge claim was substantially dependent on the CBA's just-cause provisions. The federal district court agreed and granted summary judgment for the employer on preemption grounds. The Seventh Circuit affirmed. Meanwhile, in the grievance process, an arbitrator found no just cause for the discharge and ordered Lingle reinstated with back pay. Despite the arbitral award, Lingle pursued her state tort remedy for damages. The Supreme Court granted certiorari to decide whether §301 preempts this state-law retaliatory discharge claim.
Does LMRA §301 preempt a state-law retaliatory discharge claim when the claim can be resolved without interpreting the terms of a collective bargaining agreement, even though the facts overlap with a CBA grievance and arbitration concerning just cause?
Section 301 of the LMRA preempts state-law claims that are substantially dependent upon analysis of the terms of a collective bargaining agreement or that require interpreting the agreement. A state-law claim is not preempted if it confers nonnegotiable rights independent of the CBA and can be resolved by purely factual inquiries without construing CBA provisions. Mere factual overlap with matters addressed in a grievance/arbitration, or the need to consult (but not interpret) the CBA, does not trigger §301 preemption.
No. An Illinois tort action for retaliatory discharge based on filing a workers' compensation claim is not preempted by LMRA §301 because its elements can be adjudicated without interpreting the CBA. The Supreme Court reversed the judgment of the Seventh Circuit and remanded.
The Court emphasized that the preemptive force of §301 is aimed at ensuring uniform federal interpretation of CBAs, not at displacing all state-law claims that happen to arise in unionized workplaces. The dispositive inquiry is whether adjudicating the state claim requires interpreting the CBA. Illinois's retaliatory discharge tort requires proof that (1) the employer discharged or threatened to discharge the employee, and (2) the employer's motive was retaliatory for the employee's exercise of workers' compensation rights. Resolving those elements involves factual determinations about the employer's conduct and intent, and whether the employee engaged in protected activity, none of which requires construing any CBA term. Although the CBA in this case included a just-cause provision, and the grievance process addressed whether there was just cause, the Court clarified that parallel factual questions do not transform the state claim into a contract-interpretation dispute. The existence of a CBA defense or an arbitration decision does not mandate preemption where the state claim stands on its own legal footing. The Court distinguished cases like Allis-Chalmers v. Lueck, where state tort duties were inextricably intertwined with the CBA because adjudication required interpreting contractual duties. Here, by contrast, the retaliatory discharge tort enforces a nonnegotiable state policy against punishing workers for seeking compensation benefits; its resolution neither depends on the meaning of "just cause" nor on any other CBA provision. The Court further noted that while the arbitrator's reinstatement award addressed contractual rights, the state tort enforces an independent right and may allow distinct remedies. Allowing the state claim to proceed therefore does not undermine federal labor policy; it simply preserves a separate, independent remedial track. Finally, the Court rejected the notion that the mere need to "consult" a CBA (for example, to compute damages like back pay or to ascertain background facts) triggers §301 preemption; preemption attaches only when interpretation of disputed CBA terms is required.
Lingle is the leading case articulating the modern §301 preemption test: ask whether the state claim's elements can be resolved without interpreting a CBA. It preserves state-law workplace protections for unionized employees, including public-policy torts and statutory rights, when those claims are independent of contract interpretation. The decision is frequently paired with Allis-Chalmers v. Lueck and later cases such as Hawaiian Airlines v. Norris to teach the difference between factual overlap (not preempted) and interpretive dependence (preempted). For students and practitioners, Lingle offers a practical roadmap for pleading and litigating around §301 preemption and understanding the coexistence of arbitration remedies with independent state-law causes of action.
Lingle draws a clean line: §301's preemptive force protects uniform federal interpretation of CBA terms but does not swallow state-law rights that can be adjudicated without construing those terms. By focusing on whether CBA interpretation—not mere reference or factual overlap—is required, the Court preserved state tort and statutory protections for unionized workers alongside contractual remedies.
