The Story Behind The Physiology of Bullying

After 30 years working inside complex health systems, Liza Collins witnessed a truth most organisations overlook: bullying is not a personality clash, it is a physiological injury that reshapes the brain, the body, and entire workplace cultures. The harm people carry is not imagined; it is biological, measurable, and preventable.

In The Physiology of Bullying, Liza reveals how fear, exclusion, and chronic stress silently rewire the nervous system, corrode trust, and weaken organisational performance. Combining neuroscience, trauma research, and real human stories, the book uncovers why bullying hurts so deeply and what leaders must do to end it.

This is not just a book about harm. It is a roadmap for healing, offering individuals a path back to safety and power, and challenging organisations to redesign cultures where dignity, wellbeing, and humanity are non-negotiable.
