The answer to your question depends on the era and legislation you're asking about. The US Supreme Court overturned Congress' attempts at establishing labor and wage regulation for about half a century.
During the Lochner era of the early 20th-century, the primary reason given was that legislation violated employees' substantive due process right of "liberty to contract" with an employer, as an extension of the Fourteenth Amendment. The Court also held minimum wage legislation set an artificial value on labor. While the decisions were couched in terms of constitutional protection of workers, in reality, the Court was protecting industry by helping them suppress wages.
Later, when President Roosevelt tried to establish federal control over labor conditions as part of the New Deal, the Court held Congress had overstepped its authority under the Interstate Commerce Clause, and had no right to regulate industries that operated entirely within a state (intrastate).

The Supreme Court during the early 1900s generally adopted a pro-business stance when ruling on labor issues. Key cases like Lochner v. New York (1905) held that state regulations on working hours violated workers' liberty to contract, while Adair v. United States (1908) deemed federal laws prohibiting employers from discriminating against employees based on union membership unconstitutional. These rulings undermined labor rights and unionization efforts.
