Final answer:
The three pre-Title VII laws are the Civil Rights Acts of 1866, 1871, and 1875, which laid early groundwork for anti-discrimination legislation, leading up to the comprehensive Title VII of the Civil Rights Act of 1964 that prohibits discrimination in employment.
Step-by-step explanation:
The three main pre-Title VII laws collectively known as the Civil Rights Acts of 1866, 1871, and 1875. These laws were early attempts to establish equal rights for all citizens, particularly former slaves, in the post-Civil War United States.
However, they were not as comprehensive or effective as the subsequent Title VII of the Civil Rights Act of 1964, which prohibits discrimination in employment on the basis of race, color, religion, sex, or national origin.
Title VII also includes protections against discrimination for associating with an individual of a protected class and explicitly states the unacceptability of employment practices that limit, segregate, or classify employees in ways that would adversely affect their status because of their inclusion in one of these protected categories.
