Social work supervision is a forum in which social workers and supervisors have the opportunity to explore ethics within their practice. It is also where social workers experience ongoing learning and development regarding ethics. This article is a selective review of social work supervision and ethics literature. Key areas identified are: 1) the role of supervision in the monitoring and development of ethical social work practice; 2) supervisors’ knowledge and application of codes of ethics, ethical theories, principles and ethical decision-making (...) models; 3) ethical supervisory relationships, processes and practices. A lack of research evidence was identified regarding the application of ethics within supervision and in relation to the interactional process of ethical exploration, inquiry and dialogue within sessions. Considering this lack of evidence, we propose that ethics be integrated throughout the supervision process through the development of care ethics culture, ethical sensitivity and ethical dialogue. The article concludes with recommendations about bringing ethics to the forefront in supervision. Recommendations are also made concerning further research pertaining to the monitoring and development of ethical social work practice through supervision, supervisors’ ethics knowledge, the interactional process of ethical supervisory practice with supervisees and the influence of organisational culture upon ethics and supervision.
