Compliance & whistleblower protection
Fair competition, integrity and responsibility: these are the values represented by the GLS Group as an international parcel service provider.

The GLS Code of Business Standards forms the basis for all business decisions and governs responsible interactions with all stakeholders.
We expect our suppliers and service providers to adhere to the principles outlined in the GLS Code of Conduct for Suppliers, to implement them through appropriate measures and to consistently observe them in the course of their business activities.

We focus our efforts on climate protection by reducing our resource consumption and the associated emissions. Find out more about our goals in our Environmental Standard.
At GLS, we are committed to clear ethical principles
This is a key pillar for the success of our company. All our employees therefore share the responsibility to uphold our principles. Even the misconduct of a few individuals can harm the good reputation of the entire company. That is why it is important for us to identify potential legal violations by employees, suppliers or other third parties at an early stage, so that we can respond quickly and take effective remedial action. Fair competition, integrity and responsibility: These are the values represented by the GLS Group as an internationally operating parcel service provider.
Whistleblower Protection Act – What can be reported?
Since the Whistleblower Protection Act came into force, companies are required to establish an internal reporting office. Whistleblowers can use this internal reporting channel to inform us about possible violations they become aware of in the course of their professional activities. The internal reporting office is available for the following matters:
- Information on suspected criminal offences;
- Information on suspected regulatory offences, provided the relevant rules serve to protect life, limb or health, or to safeguard the rights of employees or their representative bodies (such as works council members);
- Information on other violations within the meaning of Section 2 (1) No. 3 of the Whistleblower Protection Act (such as suspected violations of the General Data Protection Regulation when handling personal data).
Reports concerning the above-mentioned violations are subject to strict confidentiality in order to protect both the whistleblower and the individuals named in the report as effectively as possible. Whistleblowers are also legally protected against reprisals.
Internal Reporting Office for reports under the Whistleblower Protection Act and the German Supply Chain Due Diligence Act
The internal reporting office, as defined by Sections 12 ff. of the Whistleblower Protection Act, is the Compliance department.
The internal reporting office is also responsible for the complaints procedure under Section 8 of the Supply Chain Due Diligence Act (LkSG), allowing confidential reports on human rights or environmental risks as well as breaches of human rights-related or environmental obligations.
You are also welcome to contact the internal reporting office with reports not listed above. These will also be handled with strict confidentiality.
Please note, however, that as a whistleblower you are only protected if, at the time of reporting, you had sufficient reason to believe that the report you made was true. You are not protected if you knowingly make a false report.
If your enquiry concerns parcel-related complaints or data protection enquiries (not a compliance or LkSG-relevant report), please understand that we cannot process such cases via the following channels.

External Reporting
In addition to the internal reporting office, you also have the option to contact the relevant external authorities (external reporting). These include:
- As a rule, the Federal Office of Justice (BfJ) is responsible for handling your report.
- In cases defined by law, you may also contact the Federal Financial Supervisory Authority (BaFin) or the Federal Cartel Office (BKartA).

Internal or external?
Under the law, you have the option to either contact the internal reporting office first or to report directly to an external authority. Nevertheless, we kindly ask you to contact the internal reporting office initially. We take every report very seriously and strive to take effective action against any violation. If, from your perspective, your internal report has not been adequately addressed, you are of course free to then contact the appropriate external authority.
