This book investigates the systemic causes and consequences of the widespread mental health crisis among teachers in the United Kingdom during the late 20th century. John Cosgrove utilizes historical data and occupational health trends to analyze why thousands of educators left the profession due to ill health. The text provides a framework for understanding the intersection of school policy, administrative pressure, and individual psychological well-being. It argues that the high rate of burnout represents a structural failure rather than a series of isolated personal incidents.

Experts and educators often cite this work as a significant historical document regarding the state of the British teaching profession at the turn of the millennium. Readers frequently note the clarity with which the author connects individual suffering to broader systemic issues in school management.
