Cellnex ensures that its workforce is aware of and trusts the structures and processes for raising concerns through regular communication campaigns, mandatory training, and periodic feedback mechanisms, such as surveys, to assess awareness and confidence in the grievance channels. These initiatives are designed to foster trust in the system and are regularly reviewed to address any gaps and ensure concerns are effectively managed. Confidentiality and the principle of non-retaliation are emphasised to reinforce trust in the system. Cellnex has a zero-tolerance policy on retaliation, as outlined in its Code of Ethics and the Policy for the Whistleblowing Channel. These policies protect individuals who raise concerns from any form of retaliation, discrimination, or threat.
