BACKGROUND: The Ergonomic Work Analysis and Training (EWAT) network celebrated its 30th anniversary in 2021. OBJECTIVE: THE EWAT focuses mainly on how activity analysis in real work can contribute to the training situations. Over the years, two lines of thought evolved: i) training in ergonomic work analysis, and ii) the use of the work analysis for the improvement or design of training interventions. Both share a common theoretical and methodological background based on three pillars: the focus on real work, the adoption of a systemic and participatory approach, and the intentional emphasis on a multidisciplinary approach. METHODS: The design of training courses that are adequate both for workers and for supervisors who are concerned with the development of the worker’s skills and health at work is challenged by major changes at work. Such challenges were the driving force behind the discussion within this network at the IEA 2021 congress. RESULTS: The authors who contributed to this congress maintain the network’s characterizing principles. At the same time, they introduce research updates and new intervention methodologies. In addition, the authors have been called upon to provide novel answers to the issues of organizational transformation and digitalization of work and training. CONCLUSION: The permanence of this network involves leveraging its 30 years of collective expert experience to continue to respond to present and emerging challenges, concerning work and training sustainability. The network’s research contributes to growing evidence about how training can impact on healthier workplaces where individual and group development is improved.
