In the case of National Labor Relations Board v. Magnavox Company of Tennessee, 1973, the U.S Supreme Court ruled in favor of the National Labor Relations Board (NLRB). The dispute arose when Magnavox refused to bargain with a union that had been certified by NLRB as an exclusive representative for certain employees. The company argued that it was not obligated to negotiate because some employees were ineligible to vote in the representation election due to their temporary layoff status at that time. However, NLRB maintained its certification and ordered Magnavox to bargain with the union under Section 8(a)(5) and (1) of National Labor Relations Act which makes it unlawful for employers not bargaining in good faith with employee representatives. The Supreme Court upheld this order stating that NLRB's decision was within its discretion provided by Congress through legislation. It further clarified that courts should defer such matters related labor relations expertise unless there is no rational basis or inconsistent interpretation from previous rulings.

In the dissenting opinion for the National Labor Relations Board v. Magnavox Company of Tennessee case, Justice William O. Douglas argued that the majority's decision to uphold an employer's right to unilaterally change a collective bargaining agreement was fundamentally flawed and undermined labor rights. He contended that such unilateral changes should only be allowed if they were explicitly permitted by the contract itself or agreed upon in good faith negotiations between both parties involved. According to him, allowing employers this power without any restrictions would give them undue leverage over their employees and disrupts balance in labor relations as it could lead to arbitrary decisions made without considering workers' interests or input from unions representing them.
