In the case of Walling v. Jacksonville Paper Co., 1942, the U.S. Supreme Court was asked to determine whether or not certain employees of a wholesale paper and stationery company were engaged in commerce as defined by the Fair Labor Standards Act (FLSA) and thus entitled to overtime pay for hours worked beyond forty per week. The workers in question performed tasks such as loading, unloading, handling, wrapping, weighing and delivering goods that had been transported across state lines. The court ruled that these activities constituted "engaging in commerce" under FLSA's broad definition because they were closely related and directly essential to interstate commerce. Therefore, these employees should have received overtime compensation according to federal law.

In the dissenting opinion for Walling v. Jacksonville Paper Co., Justice Frank Murphy argued that the majority's interpretation of "production" in relation to the Fair Labor Standards Act was too narrow and failed to consider Congress' intent when drafting this legislation. He believed that any activity contributing directly or indirectly to commerce should be considered production, including activities such as maintenance work and transportation within a company. In his view, these tasks are essential components of producing goods for commerce and thus employees performing them should be entitled to overtime pay under federal law. The majority's decision not only contradicted previous court rulings but also undermined workers' rights by excluding certain types of labor from protection under the Fair Labor Standards Act.
