Reporting office in accordance with the Whistleblower Protection Act
Employees as well as customers, suppliers and business partners are often the first to notice possible irregularities in companies and can use their information to ensure that irregularities or offences are uncovered, investigated, pursued and stopped. Whistleblowers assume responsibility for society and therefore deserve protection from disadvantages that they may fear and therefore be deterred from reporting.
Legislators across the EU have taken action in this area and enacted the Whistleblower Protection Act (HinSchG). The primary aim is to protect whistleblowers and enable anonymous reporting. To this end, HANNO has set up a whistleblower portal. Incoming reports are only accepted by our external data protection officer.
