In the case of Maneja et al. v. Waialua Agricultural Co., Ltd., in 1954, the U.S Supreme Court ruled on a labor dispute involving Filipino agricultural workers in Hawaii who were protesting against their employer, Waialua Agricultural Company. The workers argued that they were not being paid overtime wages as required by the Fair Labor Standards Act (FLSA). However, the company claimed an exemption from these requirements under Section 13(a)(6) of FLSA which excludes "any employee employed in agriculture" from its provisions for minimum wage and maximum hours. The court had to determine whether activities performed by employees such as stripping leaves off harvested pineapple plants or cutting weeds constituted 'agricultural' work within meaning of this provision. The Supreme Court held that although some tasks performed by these employees could be considered agricultural, others did not fall into this category because they weren't directly related to farming operations but rather maintenance and general upkeep. Therefore, it was concluded that those non-agricultural duties made them eligible for overtime pay under FLSA regulations since only those whose entire employment is engaged in agriculture can claim exception under section 13(a)(6). This decision marked a significant step towards ensuring fair labor practices and rights protection for agricultural workers.

In the dissenting opinion for Maneja et al. v. Waialua Agricultural Co., Ltd., Justice Robert H. Jackson argued that the majority's decision to uphold a lower court ruling in favor of Waialua Agricultural Co., Ltd was incorrect and inconsistent with previous rulings on similar cases involving labor laws and agricultural workers' rights. He contended that the company's employees, who were primarily Filipino immigrants, should be classified as "agricultural laborers" under federal law because their work involved cultivating and harvesting pineapples - tasks traditionally associated with farming operations rather than industrial production processes. As such, he believed they should be exempt from certain provisions of the Fair Labor Standards Act (FLSA) which mandates overtime pay for non-agricultural workers who work more than 40 hours per week. Furthermore, Justice Jackson criticized his colleagues for failing to consider broader social implications of their decision including potential exploitation of vulnerable immigrant worker populations by large agribusiness corporations seeking to maximize profits at expense of fair wages and working conditions.
