Which one of the following employee behaviors most clearly violates the company policy cited above? ["never firing a family member, even though three of one's siblings work under one's supervision and authority", "refusing to hire any of one's five siblings, even though they are each more qualified than any other applicant", 'repeatedly refusing to advance an employee, claiming that he has sometimes skipped work and that his work has been sloppy, even though no such instances have occurred for over two years', "receiving over a hundred complaints about the service one's office provides and sending a complimentary product to all those who complain, including one's mother"]
