Speech and language therapists (SLTs) are generally aware of and skilled in managing ethical issues in providing services to individual clients and families. However they may struggle with ethical concerns as they strive to deliver the best possible services in the context of increasing caseload volume and complexity, changing models of service delivery, service restructures and changes in support and professional development. This paper overviews the language of ethics, approaches to ethics and ethical decision-making, as tools for SLTs to analyse, articulate and manage ethical concerns associated with changing services and professional supervision contexts, in order to advocate for their clients and services and demonstrate ethical leadership in their workplaces.
