The boundaries of the therapeutic relationship are a crucial part of effective therapy. Yet, understanding them, and the effects of power and responsibility, can be intimidating to trainee or newly-qualified therapists. This book explains everything they need to know to work ethically and safeguard the well-being of both themselves and clients. It tackles: contracting and the importance of negotiating and clarifying boundaries with clients; the implications and limits of maintaining confidentiality; keeping clear sexual boundaries, and how to work around issues safely and appropriately; what happens when circumstances change, and every day or serious disruptions occur to therapy; and the nature of the therapist's power, and how to employ it responsibly to a client's benefit. Packed with case studies, ethical dilemmas and points for reflection and discussion, this is an essential read for trainee practitioners and qualified therapists looking to ensure safe and ethical practice.
