In the case of Mitchell, Secretary of Labor v. Oregon Frozen Foods Co., et al., 1959, the U.S Supreme Court ruled in favor of James P. Mitchell, then Secretary of Labor. The issue at hand was whether or not certain activities performed by employees were considered "work" under the Fair Labor Standards Act (FLSA). These activities included time spent traveling to and from work sites as well as waiting for equipment repairs during their shifts. The court held that these activities did constitute work and should be compensated accordingly under FLSA regulations because they are an integral part of the principal activity which employees are employed to perform on any particular workday; thus making them eligible for overtime pay if those hours exceeded forty in a week.

In the dissenting opinion for Mitchell v. Oregon Frozen Foods Co., Justice Whittaker argued that the majority's interpretation of "produced" in Section 3(j) of the Fair Labor Standards Act was too broad. He contended that, under their interpretation, any activity performed by an employee would be considered as producing goods for commerce if it indirectly contributed to such production. This could potentially include activities like maintaining company records or cleaning offices - tasks which he believed were not intended to fall within the scope of this law when it was enacted by Congress. Furthermore, he expressed concern over potential implications on states' rights and federalism due to this expansive reading of a federal statute.
