Abstract
Psychological symptoms, i.e. compassion fatigue, burnout and vicarious trauma, have been found to be associated with working with clients who are experiencing trauma. The literature on the brain and neuropsychological processes that accompany trauma indicate that physiological changes also arise in the person. This paper argues that psychological and physiological changes can be transferred from the traumatised clients to those working with the traumatised person. In an organisation where there is insufficient support and high case loads this can result in physiological changes occurring in the worker that lead to three main flawed decision-making processes. Clinical practice that supports reflective supervision can help workers to process their client's trauma and prevent a traumatised professional system arising.
