In 2001, as a young university graduate, Dennis Gentilin became a member of a FX trading desk at one of Australia's largest banks, the National Australia Bank. In the years that followed the desk became involved in a trading scandal that resulted in the resignation of the chairman and CEO, the upheaval of the board of directors, significant financial loss, and incalculable reputational damage. It was in this environment that the true meaning of business ethics was revealed to Gentilin.In this ground breaking book, Gentilin draws on both his personal experience and the emerging literature in the various disciplines of psychology to provide a very unique insight into the origins of ethical failures. The intellectual depth Gentilin provides coupled with his real life reflections make this book a must read for senior leaders, regulators, consultants, students and practitioners.Amongst other things, the book highlights the shortcomings associated with the traditional approaches used to explain and address ethical failures and illustrates how easily we can all, individuals and organisations alike, be complicit to unethical conduct. More importantly, it provides lessons and guidance to all leaders who aspire to build institutions that are more resilient to ethical failure.
