Final answer:
Omar is experiencing a hostile work environment due to frequent offensive comments about his religion by co-workers and inaction by his supervisor, which is illegal under Title VII of the Civil Rights Act of 1964.
Step-by-step explanation:
Omar is experiencing a hostile work environment. This type of environment is characterized by behaviors such as frequent comments about a person's religious beliefs or practices that are offensive or unwelcome. The law, specifically Title VII of the Civil Rights Act of 1964, prohibits harassment on the basis of religion or creating a work environment that is hostile or offensive. In this situation, Omar's co-workers' comments and his supervisor's failure to address the issue despite Omar's report contribute to what is deemed a hostile work environment.
