Post-Starbucks § 10(j) Injunctions Require Independent Proof of Irreparable Harm

Introduction

In Elizabeth Kerwin v. Trinity Health Grand Haven Hosp., the Sixth Circuit addressed, for the first time after Starbucks Corp. v. McKinney, what the National Labor Relations Board must show to obtain interim injunctive relief under § 10(j) of the National Labor Relations Act.

Trinity Health Grand Haven Hospital withdrew recognition from an SEIU-affiliated union after receiving a post-election “disaffection petition,” even though employees had recently voted against decertifying the union. The NLRB Regional Director, Elizabeth Kerwin, sought a § 10(j) injunction requiring Trinity to recognize and bargain with the union while administrative proceedings continued. The district court granted the injunction. The Sixth Circuit reversed.

Summary of the Opinion

Judge Readler, joined by Judge Bush, held that the Director was likely to succeed on the merits of the unfair-labor-practice charge because Trinity’s disaffection petition was factually unreliable. But the court concluded that the Director failed to make a clear showing of irreparable harm, which is indispensable after Starbucks Corp. v. McKinney.

The court vacated the injunction because the Director did not adequately prove that, without interim relief, the Board’s eventual remedial authority would be meaningfully impaired. General assertions that refusal to bargain weakens a union were insufficient. The Director needed concrete evidence that the alleged violation would cause harm that the Board could not later remedy through its ordinary powers.

Judge Boggs dissented. He agreed that the Director was likely to succeed on the merits but argued that the district court permissibly inferred irreparable harm from record evidence showing declining union participation and altered bargaining conditions.

Analysis

1. The New Legal Rule

The decision establishes an important Sixth Circuit rule for § 10(j) cases after Starbucks Corp. v. McKinney:

  • The NLRB must satisfy the ordinary four-factor preliminary-injunction test.
  • Likelihood of success means likely success not only before the Board, but also in eventual judicial enforcement proceedings.
  • Irreparable harm cannot be inferred merely from an alleged refusal to bargain.
  • The Director must identify a specific injury, prove that it is likely and imminent, and explain why the Board’s final remedial powers cannot fix it.

2. Precedents Cited

Preliminary-Injunction Framework

The controlling precedent was Starbucks Corp. v. McKinney, where the Supreme Court rejected the Sixth Circuit’s former relaxed § 10(j) standard. Before Starbucks, the Sixth Circuit asked only whether there was “reasonable cause” to believe an unfair labor practice occurred and whether relief was “just and proper,” as reflected in McKinney v. Ozburn-Hessey Logistics, LLC. The Supreme Court held that approach was too lenient and required application of the traditional test from Winter v. Nat. Res. Def. Council, Inc..

The Sixth Circuit also relied on EOG Res., Inc. v. Lucky Land Mgmt., LLC, James B. Oswald Co. v. Neate, Munaf v. Geren, Memphis A. Philip Randolph Inst. v. Hargett, and Nken v. Holder to emphasize that preliminary injunctions are extraordinary remedies and that irreparable harm is central to obtaining such relief.

Likelihood of Success and NLRB Enforcement

The court used NLRB v. Starbucks to explain that Board orders are not self-executing. A Board victory matters only if a court of appeals later enforces the Board’s order. Therefore, likelihood of success under § 10(j) includes the likelihood that the Board’s legal and factual conclusions will survive appellate review.

Frankl v. HTH Corp. supported this broader view of likelihood of success. The court also cited Rieth-Riley Constr. Co., Inc. v. NLRB and Loper Bright Enters. v. Raimondo for the principle that courts do not defer to the NLRB’s interpretation of the NLRA.

Union Recognition and Disaffection Evidence

The merits issue concerned whether Trinity had objective evidence that the union had lost majority support. The court cited NLRB v. Galicks, Inc. for the rule that an employer violates the Act by unilaterally withdrawing recognition from a union that still has majority support.

Auciello Iron Works, Inc. v. NLRB supplied the presumption that an incumbent union enjoys majority support. Pac. Coast Supply, LLC v. NLRB and Wyman Gordon Pa., LLC v. NLRB were used to frame the burden and the need for objective evidence of actual loss of majority support.

The Director relied on Board precedents such as Macy's Inc. and Cmty. Support Network, which treat a valid Board election as overriding later evidence of employee disaffection. The Sixth Circuit was skeptical of that categorical rule, reasoning that the NLRA text does not say that election results always trump later non-election evidence.

The court distinguished Brooks v. NLRB, which had upheld a Board rule protecting a newly certified union for one year. The majority viewed Brooks as tied to certification elections and to a now-outdated deferential approach to Board policymaking.

Irreparable Harm

The central dispute concerned irreparable harm. The Director relied on cases such as Frankl v. HTH Corp. and Hooks ex rel. NLRB v. Nexstar Broad., Inc., where courts permitted inferences that refusal to bargain may weaken a union and impair the Board’s remedial authority.

The majority declined to follow that approach in the Sixth Circuit after Starbucks. It instead relied on Henderson ex rel. NLRB v. Bluefield Hosp. Co., Sharp v. Parents in Cmty. Action, Inc., and FirstEnergy, LLC v. NLRB to stress that the Board has substantial remedial powers, including bargaining orders, reinstatement, back pay, and restoration of benefits.

The court also considered Poor v. Parking Systems Plus, Inc., where the Second Circuit read Starbucks as preserving some prior irreparable-harm reasoning in § 10(j) cases. The Sixth Circuit declined to adopt that view.

Delay

Finally, the majority relied on York Risk Servs. Grp., Inc. v. Couture, Cheetah Miner USA, Inc. v. 19200 Glendale, LLC, NLRB v. Hartman & Tyner, Inc., and Boire v. Pilot Freight Carriers, Inc. for the principle that delay in seeking preliminary relief undermines a claim of urgency and irreparable injury.

3. Legal Reasoning

The court divided the inquiry into the four Winter factors.

Likelihood of Success

Trinity argued that the disaffection petition justified withdrawing recognition. The majority rejected the Director’s broad legal argument that the petition was categorically irrelevant because a decertification election had just occurred. The court found no clear statutory basis for the NLRB’s rule that a valid election always defeats later disaffection evidence.

But the Director still likely prevailed factually. The petition was weak: many signatures were recycled from an earlier decertification petition, none were dated, several pages lacked the statement of purpose, and Trinity did little to verify the signatures. Because the petition barely claimed majority support, even a few invalid signatures would defeat it.

Irreparable Harm

This was the decisive factor. The Director argued that Trinity’s refusal to bargain would weaken union support and reduce the effectiveness of any later Board bargaining order. The majority held that this theory was too speculative.

The Director’s evidence consisted mainly of union-meeting attendance data and an affidavit describing employee frustration and fear. The court found the attendance data equivocal and the affidavit too generalized. It also reasoned that many alleged harms, such as lost pay or benefit changes, could be remedied later by the Board.

The court announced a practical test: the Director must show (1) the specific threatened injury, (2) that the injury is likely without an injunction, and (3) that the Board’s final remedies cannot repair it.

Balance of Equities and Public Interest

The majority treated these factors as secondary. Trinity’s claimed burdens from bargaining were not persuasive, but neither was the Director’s showing of harm. The public-interest analysis largely overlapped with the merits because employee choice cuts both ways: employees have the right to support a union and the right to reject one.

4. The Dissent

Judge Boggs argued that the majority made the irreparable-harm burden too demanding. He distinguished between an impermissible mandatory presumption and a permissible inference. In his view, the district court did not presume harm merely from a likely violation; it drew a reasonable inference from evidence of declining union-meeting attendance, chilled union participation, and unilateral changes to employment policies.

The dissent relied heavily on Frankl v. HTH Corp., Hooks v. Nexstar Broadcasting, Inc., Henderson v. Bluefield Hospital Co., LLC, and ACT, Inc. v. Worldwide Interactive Network, Inc. to argue that courts routinely infer future irreparable harm from present facts. Judge Boggs warned that the majority’s approach creates tension with other circuits and may weaken the Board’s ability to preserve meaningful remedies during lengthy administrative proceedings.

Impact

This decision materially raises the evidentiary burden for the NLRB in Sixth Circuit § 10(j) cases. Regional Directors can no longer rely on generalized propositions that refusal to bargain inherently weakens a union. They must present concrete, case-specific evidence showing that the union’s support or bargaining position is deteriorating in a way the Board cannot later repair.

Employers, however, should not read the decision as permission to withdraw recognition lightly. The court found the Director likely to succeed on the merits because Trinity’s petition was deeply flawed. A defective disaffection petition remains risky and may support an unfair-labor-practice finding.

The opinion also signals a broader post-Loper Bright shift: courts in the Sixth Circuit will independently evaluate NLRB legal interpretations rather than defer to Board policy judgments, especially where the statutory text does not clearly support the Board’s rule.

Complex Concepts Simplified

  • § 10(j) injunction: A temporary court order the NLRB can seek while an unfair-labor-practice case is still pending.
  • Irreparable harm: Harm that cannot be fixed later by money, reinstatement, bargaining orders, or other final remedies.
  • Decertification petition: A petition asking the NLRB to hold an election on whether employees want to remove a union.
  • Disaffection petition: A non-election petition claiming employees no longer support the union.
  • Blocking charge: A union’s request to delay counting or certifying election results because alleged unfair labor practices may have affected the election.
  • Substantial evidence: A deferential standard courts use when reviewing agency factual findings.

Conclusion

Elizabeth Kerwin v. Trinity Health Grand Haven Hosp. is a significant post-Starbucks precedent. The Sixth Circuit confirms that § 10(j) relief is extraordinary and requires a concrete showing of irreparable harm. Even a strong merits case will not justify an injunction unless the NLRB proves that delay will likely cause harm beyond the Board’s power to remedy later.

The decision narrows the path to interim labor injunctions in the Sixth Circuit and underscores that, after Starbucks and Loper Bright, NLRB litigation must satisfy ordinary equitable standards and independent judicial review.
