This document summarizes an ethics lecture presented by Joseph Tojarieh on workplace ethics. It discusses how various professions, like doctors, architects, and athletes, have codes of ethics that govern conduct. For attorneys, conduct is governed by the California Rules of Professional Conduct. These rules address relationships with other attorneys, financial arrangements, communicating with represented parties, and relationships with clients, courts, and the public. The duty of confidentiality and attorney-client privilege are also discussed. The document closes by presenting an ethical dilemma case about exculpatory evidence and asking how attorneys should respond.
