D.C. Circuit Rejects NLRB “Successor Bar” for Unionized Business Acquisitions
Short summary
The D.C. Circuit invalidated the NLRB's successor bar rule, which required new owners of unionized businesses to bargain with the incumbent union for up to one year before employees could challenge its status. The court held the rule violates the NLRA by forcing employers to bargain with a union lacking majority support. Successor employers can now act on employee-presented evidence that a union no longer represents a majority.
- •D.C. Circuit struck down NLRB successor bar rule as conflicting with the NLRA
