Which act requires federal agencies and government contractors to comply with anti-discrimination practices?

The correct choice highlights Executive Order 11246, which mandates that federal agencies and government contractors adhere to anti-discrimination practices in their employment policies. This executive order, established in 1965, emphasizes equal opportunity by prohibiting discrimination based on race, color, religion, sex, or national origin in federally funded activities. It requires affirmative action to ensure equal employment opportunity, setting a legal framework that compels institutions to actively seek to eliminate discrimination in hiring and promotion practices.

The other acts mentioned address different aspects of employment law. The Uniformed Services Employment and Reemployment Act protects the rights of individuals who serve or have served in the military but does not specifically focus on the broader anti-discrimination standards required of federal contractors. The Americans with Disabilities Act prohibits discrimination against individuals with disabilities in various areas, including employment, but it is not solely focused on government contractors. Similarly, the Immigration Reform and Control Act primarily addresses issues regarding the employment of undocumented workers and does not cover the wider range of anti-discrimination requirements mandated by Executive Order 11246. Thus, this order is crucial for ensuring that federal contracts are awarded and maintained in a manner that promotes equality in the workplace.
