Which US entity would deal with affirmative action policy?

The Office of Federal Contract Compliance Programs (OFCCP) is the U.S. entity primarily responsible for handling affirmative action policies, especially within the context of federal government contracts. The OFCCP ensures that employers comply with affirmative action and equal employment opportunity requirements set forth in the laws, mandates, and regulations governing federal contracts.

This office plays a pivotal role in enforcing affirmative action regulations, which are designed to promote equal opportunities in employment for individuals regardless of race, gender, disability, or veteran status. They monitor and assess contractors' affirmative action plans to ensure implementation and compliance.

While the other entities listed have their own specific roles, they do not focus on affirmative action policies in the same capacity. For example, the National Institute for Occupational Safety and Health is concerned with workplace safety and health, the Rotary Commission is not a government body relevant to labor policies, and the Department of Commerce focuses on economic growth and trade. Therefore, the OFCCP is the most appropriate answer, as it directly engages with the enforcement and administration of affirmative action policies.
