Whistleblower Protection

We at GLS are committed to clear ethical principles. This is a pillar of our success as a business. All GLS staff bears responsibility for GLS living up to its principles; quite often, it is the misconduct of just a few that badly reflects on the reputation of a business as a whole. Hence, it is crucial for GLS to get notified of potential misconduct of its staff, its suppliers or third parties as early as possible so that we can quickly act on it and efficiently remedy the situation.

Effective September 1st, 2023, the Act no. 54/2019 Coll. on the protection of whistleblowers of anti-social activity came into force (“Act”). This Act obliges GLS to establish an internal reporting channel. Through this internal reporting channel, whistleblowers can inform GLS of potential work-related misconduct.

Whistleblowers may use the internal reporting channel to report the serious anti-social activity.

Reports which concern the offences detailed above will be treated with the utmost confidentiality to maximize the protection of whistleblowers and those mentioned in the report. In addition, the Act protects whistleblowers against any form of retaliation.

However, please be advised that, as a whistleblower, you will only enjoy the protections guaranteed by the Act if you had at the time of submitting the report sufficient reason to assume that your report was true. You are not protected when submitting a report which you know is untrue.

The internal reporting channel within the meaning of Section 5-8 and § 11 sec. 1 of the Act is Compliance.

Please contact the internal reporting channel via 1) EQS or 2) our ombudsman Dr. Rainer Buchert.

Besides contacting the internal reporting channel, you also have the possibility to contact the relevant authorities directly (external reporting). In the Slovak Republic, it is The Office for the Protection of Whistleblowers, the Prosecutor's Office or the administrative body responsible for proceedings on an administrative offence, which is a serious anti-social activity according to § 2 letter d) points 3 and 4 of the Act or the relevant institution, authority, office or agency of the European Union.

The Act allows you to choose whether you would like to contact the internal reporting channel first or whether you prefer to submit your report directly to the relevant external authority. However, we urge you to always contact us first via the internal reporting channel. GLS will investigate your report with the utmost seriousness and will try to remedy the offence. If you are still dissatisfied with the situation following the completion of our internal follow-up measures, you may still contact the external authorities.
