Final answer:
The most comprehensive U.S. law regarding worker safety is the Occupational Safety and Health Act , providing a framework for enforcing safety standards and offering related training and education.
Step-by-step explanation:
The most comprehensive U.S. law regarding worker safety is C. the Occupational Safety and Health Act (OSHA). OSHA was signed into law by President Nixon with the intention to ensure safe and healthful working conditions for men and women.
It achieves this by setting and enforcing standards, as well as providing training, outreach, education, and assistance.
While other amendments and acts, such as the Thirteenth and Fourteenth Amendments, and the Civil Rights Act of 1964 are crucial for their respective contributions to civil rights and liberties, when it comes to specifically addressing worker safety, it is OSHA that stands out as the primary legal act dedicated to this purpose.
Within the context of workplace protection laws, as mentioned in Table 14.4, many laws have been foundational, leading to further regulations and court rulings that shape the labor market. However, OSHA remains a cornerstone of worker safety legislation.
