This book provides a comparative perspective of whistleblowing systems across the world. The book begins with a discussion of the emergence of whistleblowing systems, identifying landmark events such as President Abraham Lincoln's signing of the False Claims Act and the European Union's implementation of the EU Whistleblowing Directive. Next, the book provides comprehensive chapters specific to the following industries: banking; accounting; insurance; trade and logistics; engineering, government contracting and funding; healthcare; and cybersecurity. The industry specific chapters provide pertinent information to employers, employees, academics, government policymakers and attorneys. Finally, the book concludes with a discussion of design components that make whistleblowing systems successful and assesses where there are likely to be future developments. Readers will learn from detailed examples from the United States, Europe, South Africa, South Korea, Singapore, Australia and New Zealand. Properly functioning whistleblowing systems are not only important morally, but they also ensure that banking, money and international finance will thrive. The book will find an audience among researchers, scholars, policymakers and professionals.
