Final answer:
Under Title VII of the Civil Rights Act of 1964, it is illegal to harass someone based on their religion. If KellyMarie Griffin files a complaint, the City should conduct an investigation and take action to address the issue.
Step-by-step explanation:
Under Title VII of the Civil Rights Act of 1964, it is illegal to harass someone based on their religion. Harassment can include offensive remarks about a person's religious beliefs or practices. In this case, KellyMarie Griffin has been subjected to derogatory comments about her Christian faith by her coworker, Theresa Lareau. Lareau's comments, along with the use of offensive language by other coworkers, have created a hostile work environment for Griffin. If Griffin files a complaint with the City claiming a violation of her rights under Title VII, the City should respond by conducting a thorough investigation into the matter and taking appropriate action to address the issue. The City cannot avoid liability under Title VII at this point because the harassment has created a hostile work environment and Griffin has clearly expressed her objection to the behavior.
