The U.S. Court of Appeals for the Sixth Circuit has delivered a landmark ruling that significantly raises the bar for the National Labor Relations Board (NLRB) when seeking preliminary injunctive relief against employers. In the case of Kerwin v. Trinity Health Grand Haven Hospital, decided on May 1, the appellate court dissolved an injunction previously obtained by the NLRB under Section 10(j) of the National Labor Relations Act (NLRA). This decision marks a critical shift in the judicial landscape, signaling a more rigorous application of equitable principles and a departure from the historically deferential "reasonable cause" standard that often favored the Board in labor disputes.
The ruling is particularly noteworthy as it aligns the Sixth Circuit with a growing judicial trend toward curbing the NLRB’s discretionary power. By requiring the Board to meet the traditional, stringent four-factor test for preliminary injunctions, the court has effectively narrowed the window through which the NLRB can secure immediate court orders to compel employer behavior while administrative proceedings are still pending.
The Genesis of the Dispute: Trinity Health and the Refusal to Bargain
The legal battle began at Trinity Health Grand Haven Hospital, where a labor dispute emerged following a union election and subsequent certification. The hospital, contesting the validity of the union’s representation or the circumstances of the bargaining demand, refused to engage in collective bargaining. In response, the union filed unfair labor practice charges with the NLRB, alleging a violation of Section 8(a)(5) of the NLRA, which mandates that employers bargain in good faith with authorized employee representatives.
Recognizing that administrative litigation before the NLRB can often take months or even years to resolve, the Board’s Regional Director, Thomas Kerwin, petitioned a federal district court for a Section 10(j) injunction. The goal of such an injunction is to maintain the status quo and prevent "irreparable harm" to the collective bargaining process while the underlying legal merits are debated before an administrative law judge.
The district court initially granted the injunction, ordering Trinity Health to recognize and bargain with the union immediately. The court’s reasoning relied on a more lenient standard that looked primarily at whether there was "reasonable cause" to believe an unfair labor practice had occurred. However, Trinity Health appealed this decision to the Sixth Circuit, arguing that the district court had applied an incorrect legal standard and failed to account for the heavy burden required for such extraordinary relief.
The Shift in Legal Standards: From Deference to Rigor
To understand the significance of the Sixth Circuit’s decision, one must look at the historical application of Section 10(j). For decades, several federal circuits utilized a two-part test that was highly favorable to the NLRB: whether there was "reasonable cause" to believe a violation occurred and whether the requested relief was "just and proper." This standard was often criticized by employers for being too deferential to the Board’s initial theories of a case.
However, the legal tide began to turn with the U.S. Supreme Court’s recent involvement in similar matters, most notably the 2024 decision in Starbucks Corp. v. McKinney. In that case, the Supreme Court clarified that the NLRB does not deserve special treatment when seeking preliminary injunctions. Instead, it must satisfy the traditional four-factor test used by all other litigants seeking equitable relief:
- A high likelihood of success on the merits of the underlying case.
- A demonstration that the petitioner will suffer irreparable harm in the absence of preliminary relief.
- A showing that the balance of equities tips in the petitioner’s favor.
- Evidence that an injunction is in the public interest.
In Kerwin v. Trinity Health, the Sixth Circuit applied this more demanding framework. The court found that the NLRB had failed to sufficiently demonstrate that irreparable harm would occur without the injunction. The court noted that the mere delay in bargaining, while frustrating to the union, did not automatically constitute the kind of permanent, irreparable damage to the bargaining unit that justifies bypassing the standard administrative process.
Chronology of the Kerwin v. Trinity Health Case
The timeline of the case illustrates the rapid escalation of legal maneuvers between the hospital and the federal agency:
- Initial Certification: The union was certified as the exclusive bargaining representative for a unit of employees at Trinity Health Grand Haven Hospital.
- Refusal to Bargain: Shortly after certification, the hospital declined to enter into negotiations, citing legal objections to the election process.
- NLRB Complaint: The union filed charges, and the NLRB General Counsel issued a formal complaint against the hospital.
- 10(j) Petition Filed: Seeking to force the hospital to the table immediately, the Regional Director filed for an injunction in the U.S. District Court for the Western District of Michigan.
- District Court Ruling: The district court granted the injunction, applying the "reasonable cause" and "just and proper" standard.
- Appellate Review: Trinity Health appealed to the Sixth Circuit, seeking a stay and a reversal of the injunction.
- May 1 Decision: The Sixth Circuit vacated the injunction, ruling that the Board did not meet the heightened evidentiary burden required under the traditional four-factor test.
Supporting Data: The NLRB’s Increasing Use of Section 10(j)
The Sixth Circuit’s decision arrives at a time when the NLRB, under General Counsel Jennifer Abruzzo, has significantly ramped up its use of Section 10(j) injunctions. In an August 2021 memorandum (GC 21-05), Abruzzo signaled a shift in policy, stating that the Board would aggressively pursue injunctions to protect workers’ rights during organizing campaigns and initial contract negotiations.
Data from the NLRB’s annual reports shows a marked increase in 10(j) activity over the last three years:
- In Fiscal Year 2021, the Board authorized 20 petitions for 10(j) injunctions.
- In Fiscal Year 2022, that number rose to 28.
- By 2023 and early 2024, the Board was seeking injunctions at a rate nearly 40% higher than the previous decade’s average.
Despite this aggressive stance, the success rate of these petitions in federal appellate courts has begun to fluctuate. While district courts—which are closer to the facts of the case—often grant the Board’s requests, appellate courts like the Sixth Circuit are increasingly scrutinizing the legal foundations of these orders. The Kerwin decision serves as a statistical "correction," suggesting that while the Board may be filing more petitions, the "win rate" at the appellate level may decline as more circuits adopt the Supreme Court’s stringent Starbucks standard.
Reactions from Legal Stakeholders
The Sixth Circuit’s ruling has elicited sharp reactions from both the management and labor bars.
Counsel for Trinity Health praised the decision, noting that it restores a sense of balance to labor litigation. "The court has correctly identified that a preliminary injunction is an extraordinary remedy, not a routine tool for the NLRB to use whenever it disagrees with an employer’s legal position," said a representative for the hospital’s legal team. "By requiring a showing of actual irreparable harm, the court ensures that employers are not forced into bargaining under the threat of contempt before their legal challenges are even heard by the Board."
Conversely, labor advocates expressed concern that the ruling would embolden employers to engage in "surface bargaining" or outright refusals to bargain as a delay tactic. "Every month that an employer refuses to bargain is a month where the union’s momentum dies and the workers’ collective voice is silenced," said a spokesperson for the union involved. "By making it harder to get 10(j) relief, the court is effectively giving a green light to companies to break the law and deal with the consequences years later."
Broader Impact and Implications for Employers
The implications of Kerwin v. Trinity Health extend far beyond the healthcare industry. This ruling creates a significant hurdle for the NLRB in Kentucky, Michigan, Ohio, and Tennessee—the states covered by the Sixth Circuit.
First, the decision reinforces the "likelihood of success" requirement. The Board can no longer rely on a "frivolousness" test where it only had to show its case wasn’t baseless. Now, the Board must provide substantial evidence early in the process that it will likely prevail on the merits. This requires the NLRB to conduct much more thorough investigations before even considering a 10(j) petition.
Second, the "irreparable harm" requirement has been clarified. The Sixth Circuit emphasized that the harm must be specific and imminent. For instance, the Board may need to prove that the union is actively losing members or that the employer’s conduct is so egregious that a later Board order would be "meaningless." General assertions that "justice delayed is justice denied" will no longer suffice in the Sixth Circuit.
Finally, the ruling may lead to a strategic shift in how the NLRB handles "refusal to bargain" cases. If the Board knows it cannot easily obtain an injunction, it may seek to expedite its internal administrative hearings. However, given the current backlog of cases at the NLRB, this is easier said than done.
Conclusion: A New Era of Labor Litigation
The Sixth Circuit’s decision in Kerwin v. Trinity Health Grand Haven Hospital represents a pivotal moment in the evolution of federal labor law. By tightening the standard for 10(j) injunctions, the court has reasserted the primacy of traditional equitable principles over administrative convenience.
For employers, the ruling provides a robust defense against what many viewed as "government overreach" in labor-management relations. For the NLRB, it presents a challenge to adapt its litigation strategy to a more skeptical judicial environment. As other circuits weigh in on similar disputes, the legal community will be watching closely to see if the "tightening" seen in the Sixth Circuit becomes the universal standard for labor injunctions across the United States. In the interim, the Kerwin decision stands as a clear signal: the era of easy injunctions for the NLRB is likely coming to an end.
