What are the collective bargaining obligations of an employer that purchases an ongoing business whose employees are currently represented by a labor organization? Under well-established NLRB case law, assuming that the new employer continues to operate a similar business and a majority of the employees hired by the new employer to operate the business are former employees of the predecessor employer, it will be deemed a “successor” to the former company. While it is free to initially establish its own wages and benefits and is not bound by the prior collective bargaining agreement with the union, it will be deemed to have an obligation to bargain with the union. What has been less clear, however, is whether that obligation to bargain can be challenged by the new employer, the employees, or a rival union if there is a good faith doubt that the union actually represents a majority of the current employees.
As is true of many issues under the National Labor Relations Act, the NLRB’s approach to the issue has not been consistent. Presently, under the Board’s “successor bar” doctrine, when a successor employer acts in accordance with its legal obligation to recognize an incumbent representative of its employees, the previously chosen representative is entitled to represent the employees in collective bargaining with their new employer for a reasonable period, without challenge to its representative status. This approach was adopted by the Board in UGL-UNICCO Serv. Co., 357 NLRB No. 76 (2011) (citing St. Elizabeth Manor, 329 NLRB 341 (1999)), which had been overruled by MV Transp., 337 NLRB 770 (2002). In UGL-UNICCO, the Board observed that the successor bar creates a conclusive presumption of majority support for a defined period of time, preventing any challenge to the union’s status, whether by the employer’s unilateral withdrawal of recognition from the union or by an election petition filed with the Board by the employer, by employees, or by a rival union.
Two recent developments give employers who find themselves in this situation some potential new options if there appears to be doubts about the union’s majority status. On July 21, 2026, the Court of Appeals for the D.C. Circuit decided Hosp. Menonita de Guayama, Inc. v. NLRB, Nos. 22-1163 & 22-1180, 2026 U.S. 2026 WL 2093902 (D.C. Cir. July 21, 2026). In this case, which had been remanded to Court of Appeals by the Supreme Court following that Court’s decision in Loper Bright Enters. v. Raimondo, 603 U.S. 369 (2024) a majority of the three-judge panel granted the Hospital’s Request for Review of the underlying NLRB decision stating:
The Board’s successor bar compels an employer who acquires a business to recognize and bargain with an incumbent union for up to one year, even if the union lacks majority support. The successor bar thus contravenes the Act by suspending two statutory protections: employees’ right to choose whether and how to collectively bargain and their right to be represented by a union that has majority support. Moreover, we reject the Board’s arguments that it has “policymaking” authority to suspend these guarantees of the Act. We therefore grant the Hospital’s petition because the Board acted contrary to law when it applied the successor bar, refused to consider the Hospital’s evidence that most of its employees rejected representation by the Union, and found the Hospital liable for an unfair labor practice.
Hosp. Menonita de Guayama, Inc., 2026 U.S. App. LEXIS at *5.
Since every adverse decision issued by the NLRB may be the subject of a Request for Review in the D.C. Circuit, employers who find themselves on wrong end of an NLRB ruling based on the “successor bar” doctrine will want to promptly pursue this course of action.
However, it also appears likely that the Board itself may soon abandon its own view of this doctrine. In the NLRB’s Weekly Summary of Cases for March 23–March 27, 2026, this case was included:
Town & Country Foods (19-RM-364265) Helena, MT, March 26, 2026. The Board denied the Employer/Petitioner’s Request for Review of the Regional Director’s Decision and Order as it raised no substantial issues warranting review. Members Murphy and Mayer noted that in the absence of a three-member majority to revisit UGL-UNICCO Service Co., 357 NLRB 801 (2011), they had applied that case as extant precedent.
Members Murphy and Mayer adhered to a longstanding, but voluntary approach to overruling precedent that they would not do so unless three members (a quorum of a full Board) agreed to do so. On August 7, 2026, a third Republican member (James Macy) along with the reappointment of the one current Democrat member (David Prouty) were confirmed to new five-year terms. It is now expected that the three Republican members will seek to overturn many of the previous decisions of the “Biden” Board which were viewed by the business community as improperly tilting the scales in the favor of organized labor. Of course, considering the recent Supreme Court decision in Trump v. Slaughter, 146 S. Ct. 2283 (2026), a Board member’s term can be cut short by the President at any point, so a change in administrations can bring about a rapid change in who is in control of the NLRB.
