Gaslighting is a covert form of psychological abuse which earns its name from a 1944 film in which a woman is made to question her sanity so that her husband can steal her jewels. With workplace bullying legislation becoming more likely, abusers will find more covert ways to control their own work environment. This book reviews what gaslighting is like for the victim, and defines the critical features present in gaslighting. This book also theoretically examines why perpetrators may be utilizing this style of abuse. This research finds that gaslighting occurs as a defense mechanism to those from high power, high individualism, and assertive cultural dimensions. Lastly, from the perspective of management, structures such as cultural dimensions were implicated in prevention as well as intervention where gaslighting has been identified.
