Internal Whistleblowing Systems: Best Practice Principles for Public and Private Organisations

Access to Guide for uncovering corruption, fraud, mismanagement and other wrongdoing added to PMWL

10 March 2023 – Access to a new resource has been added to the PM World Library (PMWL) related to fighting corruption.  The resource titled “Internal Whistleblowing Systems: Best Practice Principles for Public and Private Organisations” is a report issued by Transparency International in November 2022.

According to the report’s Introduction: Whistleblowing is the disclosure of information about suspected wrongdoing to individuals or entities believed to be able to effect action. Organisations themselves are often best placed to deal with wrongdoing occurring within their remit, and in practice, most whistleblowers first report such suspected wrongdoing within their organisation. It is therefore essential that organisations, whether private companies or public institutions, provide safe and effective mechanisms to receive and address these reports, as well as robust protection to whistleblowers.

Consequently, an increasing number of national laws require organisations to implement internal whistleblowing systems (IWS), also known as “speak up” or internal reporting systems. This has been the case since December 2021 in EU countries, for example, under the EU Whistleblower Protection Directive.

But organisations should not consider IWS as just a legal obligation. Effective IWS help protect organisations from the effects of misconduct – including legal liability, lasting reputational harm and serious financial losses. By enabling personnel and other relevant stakeholders to speak up about unethical or illegal conduct, IWS foster an organisational culture of trust, transparency and accountability. They therefore provide real benefits to an organisation’s culture, brand, value creation and growth.

This publication aims to support organisations’ implementation of effective internal whistleblowing systems. It also seeks to help organisations operating within the EU to meet their obligations under the EU Directive on Whistleblower Protection
