In communication, ethics work to enhance credibility, improve the decision-making process and allow for trust between the two parties. Ethics provide the groundwork for right and wrong, allowing two parties to communicate with a basic understanding of what is expected.
The purpose of ethics is to avoid doing harm and this is vital in communication because it works to build trust. This allows both parties to define what is acceptable to allow for better relations between individuals and different departments, in the case of organizations. The same level and understanding of ethics applies to all forms of communication, including verbal, written and digital.
