This article aimed to explore the current ethical issues in counseling through the supervisors' voices. Seven Korean supervisors were interviewed and pointed out a supervisor's lack of preparation for supervision, conflicts and dual relationships between a supervisor and a supervisee, inappropriate client assignment, and screening an impaired or unqualified supervisee as ethical dilemmas. Some of those ethical issues were caused by problematic management of counseling centers with practicum students and interns. This article could be utilized to educate supervisors and to revise Korean codes of ethics. Suggestions for future research regarding ethics to various counseling settings were made.
