Undergraduate social work students are exposed to ethical and legal dilemmas during their fieldwork training. This article presents a study that examined these ethical dilemmas in an Israeli sample of undergraduate social work students. 117 students who participated in a course in ethics submitted 31 written presentations of ethical-dilemma analysis. Their oral presentations were recorded and transcribed. Using a qualitative analysis, three major themes emerged: 1. The tension between the duty to maintain client's confidentiality and its violation under certain conditions; (...) 2. The students’ conflict of loyalty toward the client vs. the organization; 3. The question of the clients’ right to self-determination when, in the student's view, this is against their best interests.Our findings point to the vital role of an ethics course in the social work undergraduate curriculum that can enhance students’ knowledge of specific laws relevant to the limits of confidentiality in social work and their ability to analyze ethical dilemmas as future professionals. Furthermore, it is essential to raise awareness in educators and supervisors concerning moral distress that may afflict students coping with ethical dilemmas at this early professional developmental phase.
