Contact point for compliance violations

In order to clarify potential compliance violations, ZENTRAG maintains an open whistleblower culture. ZENTRAG employees as well as external third parties (such as business partners, suppliers, employees of suppliers, etc.) therefore have the opportunity to report violations of the law, violations of the ZENTRAG Code of Conduct or other ZENTRAG internal guidelines. In order to process such reports, ZENTRAG has set up a standardized process according to which anyone can report grievances anonymously or by name. ZENTRAG guarantees the confidentiality of the reports at all times.

In addition, ZENTRAG has established a grievance mechanism through the channels listed below, which also enables people along the supply chain to report grievances such as human rights violations, environmental law violations, lack of occupational safety or non-payment.
