Final answer:
The three acts are related to labor laws and worker protections; Davis-Bacon Act for prevailing wages, Walsh-Healey Act for federal contract labor standards, and Service Contract Act for service contract labor standards.
Step-by-step explanation:
The three public service acts the question refers to are likely pieces of New Deal legislation aimed at regulating labor relations and protecting workers' rights. Although there may be confusion in the question as the acts listed are not explicitly known by those names, here are the closest related acts:
- Davis-Bacon Act (1931) which requires the payment of prevailing wages on public works projects.
- Walsh-Healey Public Contracts Act (1936) that establishes labor standards for goods manufactured under federal contracts.
- The Service Contract Act (also known as the Service Contract Labor Standards Statute), which outlines wage and labor standards for service contracts with the federal government.
Overall, these acts contribute to regulating labor disputes, preventing employer discrimination against union members, and ensuring fair wages and working conditions.
