Reporting channels for whistleblowing systems

The different reporting channels for whistleblowing systems

As you could already read in Part 2 of our Whistleblowing Basics series “The Whistleblowing System”, the whistleblowing system is the core element of a compliance management in the company. There are different reporting channels that could be considered for whistleblowing. It is an internal reporting channel that allows employees to report violations of law or unethical behaviour within the company.

In addition to the basic introduction of a whistleblowing system, the EU Directive on Whistleblower Protection stipulates that confidentiality must be maintained throughout the processing of the report. Although enabling anonymous reporting is not obligatory according to the directive, it is a clear recommendation from practice for implementation. At the same time, direct communication between the whistleblower and the responsible person in the company is necessary, not only to confirm the receipt of the report, but also to be able to communicate the results of the investigation. 

Which reporting channels exist for whistleblowing in the company? 

You will find a variety of whistleblowing systems on the market. The EU Whistleblowing Directive gives your company the free choice in terms of the system’s design – provided that the reporting channel meets the Directive’s requirements. The best known and most important channels for whistleblowing are the following: 

  • Call centre: a hotline for reports via phone
  • Ombudspersons: impartial, external mediators
  • Mailboxes: written communication
  • Online solutions: Digital whistleblowing systems

What are the advantages and disadvantages of each of these reporting channels? 

The call centre: The whistleblowing hotline

The call centre is one of the classic reporting channels for whistleblowers. The advantages: with outsourcing the hotline abroad, it is possible to make it available around the clock and throughout the year. Whistleblowers are offered personal communication with a neutral person. This person can ask the whistleblower specific follow-up questions while the report is still being processed. The disadvantage, however, is that personal communication increases the inhibition threshold for whistleblowers. Statistics show that the proportion of reports made by telephone is steadily decreasing. Another difficulty is the lack of opportunity for the anonymous whistleblower to check the report made by the call centre employee in writing. Misunderstandings of language or content carry the risk of false or distorted information being transmitted. If anonymity is maintained, it is hardly possible to provide additional supporting information such as documents or photos.  

The ombudsperson

Ombudspersons are external persons of trust, usually lawyers, who are engaged by the company to act as an impartial, neutral contact for whistleblowers. Receiving reports is classically facilitated by email or phone call, with the lawyer’s time capacity being a limiting factor. The advantage is that the ombudsperson can also directly deal with the legal assessment and investigation of a report. Even though the ombudsperson as a lawyer is sworn to confidentiality, a lack of trust or a lack of possibility to report completely anonymously can trigger an additional inhibition threshold for potential whistleblowers. 

The letterbox

The letterbox, often also known as a grievance or suggestion box, allows written reports confidentially and anonymously. The big problem: in the case of an anonymous report, contact with the whistleblower is impossible, i.e. also queries or transmission of information. Because of this, the letterbox cannot be used in accordance with the Directive: both the confirmation of receipt and the transmission of information on results or follow-up measures are required by the Directive.  

Online solutions

Digital whistleblowing systems are mostly online solutions specifically developed for whistleblowing. They combine the advantages of the previously mentioned reporting channels: Digital whistleblowing systems allow anonymous and confidential reporting from any internet-enabled device. They are available 24/7, 365 days a year. Furthermore, the whistleblower can upload supporting materials, such as documents or images. Through a secure real-time chat, the whistleblower can be asked questions and receive information after the investigation – his identity remains anonymous the whole time.
