Occupational health nursing is one of the most important areas of health care. Nurses play an indispensable role in organisations, providing care and helping to prevent accidents at work and occupational illnesses, since their work ranges from the prevention of occupational illnesses to accidents at work. In view of this, the purpose of this book is to discuss, based on a bibliographical survey, the duties and contributions of occupational health nurses in the context of stress in managerial roles.
