In Esinel Ingenieros we value and appreciate the contribution of the complainants, since through their alerts we can act to prevent or stop the reported behaviors and the damage they can cause to Esinel, to the same workers, consultants, contractors, suppliers, customers, as well as to the communities that are related to the Company.

The operation of the Complaints Channel is based on the principles of confidentiality of the identity of the persons involved; objectivity in the development of the investigation; impartiality in the conclusions reached in the investigations, non-discrimination with respect to the complainants, in the recommendation of measures, and fundamentally on the principle of non-retaliation against those who, in good faith, have made a complaint or collaborated in an internal investigation.

Esinel Ingenieros undertakes that the identification of any whistleblower will always be kept strictly confidential, even in cases where the whistleblower has not made the complaint anonymously, and will only be disclosed to those conducting the investigation when necessary to ensure the success of the investigation. Likewise, the facts reported, the conduct of the investigation, the name of the accused and the recommended disciplinary action, if any, will be kept confidential.
