What type of laws affect employment practices in the U.S.?

The correct answer is federal laws because they establish a foundational framework for employment practices across the entire country. Federal laws govern various aspects of employment, such as discrimination, wage and hour standards, workplace safety, and family leave, ensuring that standards are consistent nationwide. Examples include the Fair Labor Standards Act, Title VII of the Civil Rights Act, and the Americans with Disabilities Act, all of which aim to protect workers' rights and promote fair treatment in the workplace.

While state and local laws can provide additional protections or address specific employment issues within their jurisdictions, they must operate within the boundaries set by federal laws. International laws, while they may influence business practices for companies operating globally, do not directly impact employment practices within the U.S. Therefore, understanding the role of federal laws is essential for navigating employment practices effectively.
