Which of the following adjusters is violating the adjuster code of ethics?

While Karl's actions may seem unethical, he is still conducting an investigation, which is a part of his responsibilities as an adjuster. Not disclosing the insurer's suspicions does not inherently breach the code of ethics, as adjusters must sometimes keep certain information confidential during investigations to protect the integrity of the process.

Amy's actions demonstrate a prompt and transparent approach to handling claims, which aligns with ethical standards. She is fulfilling her duty by providing clarity on damages and coverage before issuing payment, thereby maintaining ethical conduct in her role.

Although Johnny's action may raise concerns about transparency, it does not necessarily violate the adjuster code of ethics. There are situations where adjusting investigations require discretion and confidentiality, and interviewing witnesses without notifying claimants can sometimes be justified to gather unbiased information.
