Which of the following is not a protected class under federal law concerning harassment?

The choice identifying hair color as not being a protected class under federal law concerning harassment is accurate because federal anti-discrimination laws, such as Title VII of the Civil Rights Act and the Age Discrimination in Employment Act (ADEA), specifically outline certain characteristics that are protected from discrimination and harassment. These protected classes typically include race, age, disability, color, religion, sex, and national origin.

While race, age, and disability are explicitly mentioned in the context of anti-discrimination laws, hair color does not fall under these federally protected categories. This means individuals can potentially face discrimination based on hair color without the same legal protections against harassment that apply to the other listed categories.

Moreover, defining harassment and discrimination in the workplace involves recognizing the legally defined protected classes to safeguard individuals from unjust treatment. Since hair color is not considered a fundamental characteristic tied to systemic bias or oppression in the same legal framework as race or disability, it does not receive protection under federal law, making the selection of hair color the correct choice in this context.
