The new level of collaboration aims to: a) guarantee core labour rights across all Acciona sites and subcontractors; b) promote occupational health and safety thru proactive hazard identification, risk reduction, and worker-led safety initiatives; c) strengthen social dialogue by establishing mechanisms for regular consultation and communication between Acciona management and BWI-affiliated unions; and d) support and mature industrial relations arrangements by promoting access to sites, accessible, fair, and timely processes for addressing workplace issues, with union involvement and protection against retaliation.

With climate justice as BWI’s top priority, the agreement also included advancing collaboration on clean construction, decarbonisation, sustainable development, and climate resilience by aligning labour practices with Acciona’s climate and social impact goals, and promoting worker-centred just transition principles and inclusive growth.
