Final answer:
Title VII of the Civil Rights Act of 1964 and subsequent legislation protect individuals from employment discrimination based on race, color, religion, sex, national origin, and other characteristics, ensuring fair practices in hiring and pay.
Step-by-step explanation:
The practice that involves protected classes including race, color, religion, sex, national origin, ancestry, familial status, or disability falls under Federal anti-discrimination laws.
Specifically, Title VII of the Civil Rights Act of 1964 makes it an unlawful employment practice for an employer to discriminate based on these characteristics with respect to compensation, terms, conditions, or privileges of employment.
Additionally, this law has been expanded upon with subsequent legislations that strengthen protections against pay discrimination. These laws restore protection for pay discrimination claims on the basis of sex, race, national origin, age, religion, or disability, ensuring equality within the workplace.
