Step-by-step explanation:
When evaluating the employee's complaint, HR should consider Title VII of the Civil Rights Act of 1964. Title VII prohibits employment discrimination based on race, color, religion, sex, or national origin. In this case, the display of the Confederate flag could be seen as creating a hostile work environment for the African-American employee, as it represents racism and is offensive to many.
