To address the fragmentation (or lack) of whistleblowing law in Europe, the E.U. has sought to harmonize whistleblowing protection with a new directive. Meanwhile, the U.K. government has stated it does not intend to implement the directive in light of the U.K.’s withdrawal from the E.U. In this guest article, Sidley Austin attorneys Sara George, David Smith, Lauren Cuyvers and Isaac Lara contrast the position under the new Directive and in the U.K. with the position in the U.S. where, unlike in Europe, financial incentives are available to whistleblowers in certain circumstances. They consider recent developments and enforcement trends, and provide practical steps companies can implement to help ensure robust and effective whistleblower protection and in turn minimize the risks associated with wrongdoing.
