In the 1943 case of General Committee of Adjustment of the Brotherhood of Locomotive Engineers for the Missouri-Kansas-Texas Railroad v. Missouri-Kansas-Texas Railroad Co., et al., a dispute arose over whether or not certain employees were entitled to overtime pay under their collective bargaining agreement with their employer, The Missouri-Kansas-Texas (MKT) Railroad Company. The Supreme Court ruled in favor of MKT, holding that it was within its rights to interpret and apply its own contracts without interference from outside parties unless there is clear evidence that it has violated those agreements. This decision reinforced an important principle: while labor unions have a right to negotiate on behalf of workers, they cannot dictate how employers manage their businesses unless specific provisions are included in collective bargaining agreements.

In the dissenting opinion for this case, it was argued that the majority's decision to allow a union committee to sue on behalf of an employee without his consent violated basic principles of representative democracy. The dissenting justices believed that allowing such suits would undermine individual rights and give too much power to unions. They also expressed concern about potential conflicts of interest between unions and their members, noting that a union might pursue litigation not in the best interests of an individual member but rather for its own institutional benefit or political agenda. Furthermore, they disagreed with the majority's interpretation of relevant federal law as implicitly authorizing these types of lawsuits by unions. Instead, they contended that Congress had intended to protect individuals' right to control their own legal claims against employers.
