Book excerpt: This book addresses the contemporary aspects of employee voice through theoretical and practical analysis. In addition to case studies of employee voice in the workplace, it also looks at emerging forms of voice associated with the use of technology such as social media. Because of the breadth of the concept of employee voice, the focus of the book lends itself to an international perspective on employment relations and human resources management – analyses and experiences drawn from one country will be usefully considered or applied in relation to others.
