What role do personal data play in building and advancing an equitable and inclusive culture within any organisation—and how can we ensure that the collection and processing of such data meaningfully support these goals without compromising the rights of employees or other stakeholders? This training, designed primarily for professionals working in HR, data management, and compliance, explores the ethical and practical aspects of collecting, handling, and communicating diversity-related data. Together, we will examine how to approach data responsibly and strategically in order to design and implement sustainable diversity, equity and inclusion initiatives—ensuring transparency, trust, and fairness at every step.
