How do you implement a Just Culture?
Start with jointly agreed boundaries and a small, fully functional reporting and learning process.
First map out how people are reporting now, where there is fear or uncertainty and how previous cases have been treated. Then draw up simple rules together with employees and relevant representatives: what do you report, through which channel, who sees the information, how the investigation takes place, where is the behavioral limit and how can someone have a decision reconsidered.
Train managers and researchers with realistic examples. Practice the process, handle the first reports visibly carefully and publish anonymized learning points and progress. Measure trust and follow-up and adjust the process. Better to start small and complete than with a large program without capacity. EASA advises organizations to include clear Just Culture processes in their safety policies and to involve employee representatives. See the EASA Guidance for Reporting Systems.
