RC Aluminum Industries, Inc. v. National Labor Relations Board

**What Happened:** Two related companies, RC Aluminum Industries and RC Erectors, refused to bargain with a union that represented their installation workers. The union argued that since the companies were closely related, they should be treated as one employer and required to negotiate together. The companies disagreed, claiming they were separate businesses that didn't have to bargain collectively. **What the Court Decided:** The D.C. Circuit Court of Appeals sided with the National Labor Relations Board (NLRB) against the companies. The court found that RC Aluminum Industries and RC Erectors were so closely connected that they should be treated as a single employer. This meant they were legally required to bargain with the union representing workers from both companies together as one group. **Why This Matters for Workers:** This ruling protects workers when companies try to avoid union negotiations by claiming they're separate businesses. When related companies share ownership, management, or operations, courts can require them to bargain together. This prevents employers from using corporate structures to weaken workers' collective bargaining power and ensures unions can represent all affected workers effectively, even across multiple company names.
