SpeakUp reporting system

Reports can also be made (anonymously) via the established SpeakUp reporting system. There is an option to submit a violation online in written form or to report it via telephone. When reporting a violation, both the Privacy Policy for using SpeakUp and the SpeakUp Guidelines (Procedural Rules) for handling complaints and suspected compliance cases apply.

The German legislature attaches particular importance to the internal reporting of compliance violations and expressly prioritizes this over external channels.
