Code of Business Standards

The trust GLS receives from customers, employees, business partners and the public is a top priority for the GLS Group.

To further strengthen this trust, the GLS Group has assigned itself a Code of Business Standards that establishes the fundamental values and standards of behaviour of the company in binding form for all employees.

The GLS Code of Business Standards forms the basis of all business decisions and regulates responsible interaction with all stakeholders.

Whistleblowing / Ombudsman System

The GLS Group has implemented a whistleblowing/ombudsman system to enable employees, business partners and third parties to report in confidence any concerns that they have about criminal acts and similar serious offences.

On such matters all employees, business partners and third parties may contact the

Attorney Dr Rainer Buchert
Kaiserstraße 22
60311 Frankfurt am Main
Tel: +49 69 710 33 330 or +49 6105 92 1355
Fax: +49 69 710 34 444

Dr Buchert will not consider complaints concerning matters which are not of a criminal or similar serious nature. When in doubt, he will advise on how to proceed.

All complaints will be treated in confidence. Dr Buchert is required by his statutory lawyers’ confidentiality obligations not to disclose the identity of callers without their explicit consent to do otherwise. He also has the right to refuse to give evidence (including the identity of whistleblowers) if requested by a court of law. Complaints to the ombudsman will only be passed on to the GLS Group once the consent of the complainant has been received.

Of course, concerns in respect of the above matters can also be reported to an employee's line manager or other contact person within the GLS Group.
