6th Cir.

Kerwin v. Trinity Health Grand Haven Hosp.

May 1, 2026 ·24-1975 ·2-1 ·Judge Readler · By Aisha Johnson

The Sixth Circuit reversed a district court's grant of a preliminary injunction under Section 10(j) of the National Labor Relations Act, holding that the NLRB failed to demonstrate the irreparable harm required for equitable relief. While the Board likely succeeded on the merits of its unfair labor practice claims, the court found that the Board's remedial powers were sufficient to address any injury without immediate judicial intervention.

Trinity Health Grand Haven Hospital, a community hospital in western Michigan, acquired a facility that previously had an established relationship with a union representing its employees. After the collective bargaining agreement expired and negotiations stalled, employees filed a decertification petition. The NLRB ordered an election, which the union won. Shortly after the election results were certified, Trinity Health announced it would no longer recognize the union, citing a separate 'disaffection petition' with 94 signatures that it claimed proved the union had lost majority support. The NLRB's Regional Director filed unfair labor practice charges, arguing Trinity violated the National Labor Relations Act by unilaterally withdrawing recognition without objective evidence of lost support. The district court granted the Director's request for a preliminary injunction under Section 10(j) of the NLRA, ordering Trinity to resume bargaining. Trinity appealed, arguing the district court applied the wrong legal standard and that the Board failed to prove irreparable harm.

The court analyzed the case under the four-factor test for preliminary injunctions mandated by the Supreme Court in Starbucks Corp. v. McKinney. First, regarding likelihood of success on the merits, the court agreed with the district court that the Director likely succeeded. The disaffection petition was riddled with defects, including recycled signatures, missing dates, and lack of purpose statements, failing to provide the 'objective evidence' required to justify withdrawing recognition. Second, the court focused heavily on the irreparable harm factor. The majority rejected the Director's argument that irreparable harm could be inferred solely from the nature of a refusal-to-bargain violation. Instead, the court held that the Board must make a 'clear showing' of certain and immediate harm that the Board's own remedial powers cannot fix. The court found the Director's evidence—meeting attendance numbers and a witness affidavit—equivocal and speculative. The Board has broad authority to order back pay, reinstatement, and bargaining orders, meaning any harm to the union's bargaining position can likely be remedied after the administrative process concludes. Third, the court noted the Director's four-month delay in seeking the injunction undercut the claim of urgency. Finally, the balance of equities and public interest were deemed neutral, as the public interest in industrial peace does not outweigh the requirement for clear proof of irreparable harm.

The injunction ordering Trinity Health to resume bargaining is vacated. The labor dispute will now proceed through the NLRB's administrative process, where the Board will issue a final order if it finds an unfair labor practice occurred. Employers in the Sixth Circuit can no longer rely on a categorical presumption that a refusal to bargain automatically constitutes irreparable harm; they must now meet the full four-factor test with specific evidence of harm. The decision clarifies that the Board's remedial powers, including back pay and bargaining orders, are sufficient to cure most injuries without the need for immediate judicial intervention.
