RDH is commited to respecting human and labour rights, and promoting safe and fair working conditions for workers in our supply chain – vendors, subcontractors, subconsultants and partners, Despite cultural and legal differences among countries where we conduct project work or source goods, we require  all of the businesses who are part of our supply chain to uphold a consistent set of policies as outline herein. Where our code of ethics and expectation of our supply chain  conflicts with local laws, the businesses  are required to follow the stricter regulations. We believe that by being ethically aligned from the outset , we create the foundation for successful long-term relationships to achieve our mutual goals.

Our Code of Ethics is a living document that we update regularly to keep on top of emerging regulation and leading practices. It is based on industry-recognized principles and international standards, including the INTERNATIONAL LABOUR ORGANIZATION’S conventions, the UNIVERSAL DECLARATION OF HUMAN RIGHTS, the UNITED NATIONS GLOBAL COMPACT and GUIDING PRINCIPLES, the FAIR LABOR ASSOCIATION’S LABOR STANDARDS, and the CALIFORNIA TRANSPARENCY IN SUPPLY CHAINS ACT.

We want to hear from you if you have input or complaints related to human rights in our business activities. Please contact us at ethics@rdh.com with details, and we will investigate and follow up. Complaints may be anonymous and in any language.

  1. Lack of transparency, disclosure, and cooperation
  2. Forced labour
  3. Minimum wage violations
  4. Child labour
  5. Corruption and bribery

RDH requires that all businesses within its supply chain be open, transparent, and cooperative by allowing full access to facilities and provide full disclosure on all practices, locations, and resources related to projects.
