The U.S. Supreme Court case National Labor Relations Board v. Cabot Carbon Co., et al., 1958, dealt with the issue of whether an employer's refusal to bargain collectively with a union over pension and insurance plans constituted unfair labor practices under the National Labor Relations Act (NLRA). The court held that such refusal did constitute unfair labor practices as it violated Section 8(a)(5) of NLRA which requires employers to negotiate in good faith about wages, hours, and other terms or conditions of employment. This includes fringe benefits like pensions and insurances which are part of compensation for work performed by employees. Therefore, the court ruled in favor of the National Labor Relations Board (NLRB), stating that Cabot Carbon Company was obligated to discuss these matters with its employee representatives.

In the dissenting opinion for the case of NATIONAL LABOR RELATIONS BOARD v. CABOT CARBON CO., Justice Frankfurter, joined by Justices Burton and Harlan, argued that the majority had overstepped its bounds in interpreting labor law. They contended that it was not within their purview to decide whether or not a company's refusal to bargain with a union constituted an unfair labor practice; rather, this determination should be left up to Congress and administrative agencies like the National Labor Relations Board (NLRB). The dissenters also criticized what they saw as an overly broad interpretation of "bargaining collectively," arguing that such expansive readings could lead to undue interference in private business affairs. Furthermore, they disagreed with the majority's assertion that Cabot Carbon Co.'s actions were inherently destructive of important employee rights; instead, they believed these matters should be evaluated on a case-by-case basis considering all relevant circumstances.
