The book is a systematic exploration of workplace bullying, the so-called phenomenon of mobbing. Work, a crucial factor for achieving full social integration of the individual, is under attack in the context of the expansion of precarious forms of employment, the erosion of labor rights, and the intensification of unemployment during a long period of economic crisis and broader socio-economic changes, resulting in the rise of systematic negative behaviors and attitudes in the workplace. The book addresses the causes that drive the phenomenon of mobbing in workplaces, the stages of its escalation, its forms of manifestation, the characteristics of the perpetrator and the victim (sometimes plural), the destructive consequences it brings to the victims, their families, and the businesses/organizations themselves, the institutional protective framework, and the ways of prevention and management. This book comprehensively informs the reader and provides the information needed to identify a bullying work environment and the problematic behaviors that compose it, to know the rights of mobbing victims and the recommended ways of action and reaction to address and prevent the phenomenon at both institutional and individual levels. It is addressed to employees, employers, state agencies, and of course to young people, students, and every active citizen.
