  The Decolonising Digital Design project was born out of the conviction that children and young people have the right to digital spaces that are safe, fair, and respectful of their diverse cultural identities.
- Fact or Fiction: Developing Inquiry and Critical Thinking Skills in Youth
  Our mission is to inspire youth aged 12-19 to practice intelligent disobedience—doing what’s right despite pressures. Our main objective is to equip adolescents with the skills to confidently navigate the rapidly evolving digital environment and develop key competencies and digital resilience for independent functioning in adulthood. The project will be based on the participatory approach to ensure our workshop scenarios are evidence-based and address the real needs of today's youth and educators. Outputs’ testing and implementation will equip participants with essential critical thinking skills for navigating a complex online world. On-site and international online multiplier events will ensure widespread dissemination of our activities and results, amplifying the impact among adolescents and educators. Participants will explore social impact, cognitive biases, and topics like economics and online culture, sharpening their ability to distinguish facts from opinions. Educators will gain insights into digital education tools and strategies for nurturing students’ CT and information verification skills. Deliverables include 18 CT workshops for youth, supported by a report with themed scenarios and exercises for integrating CT skills into daily lessons.

- Study on the ‘Repercussions of US agri-food tariffs on EU regions’

In this project commissioned by Eurofound, CASE will carry out a comprehensive EU-wide analytical study on the drivers and underlying causes of involuntary part-time employment across EU Member States. The project will aim to deepen understanding of why a significant share of workers are unable to access full-time employment and how labour-market structures, institutional settings and policy frameworks contribute to this phenomenon.

The study will examine trends and patterns of involuntary part-time work across countries and population groups, analysing differences by gender, age, sector and contractual arrangements. Particular attention will be paid to the interaction between labour demand, job quality, working-time arrangements and social protection systems, as well as to the role of national labour-market regulations and employment policies in shaping involuntary part-time employment.

By combining quantitative analysis of EU-level labour market data with comparative analysis of national policies and institutional frameworks, the project will provide a robust assessment of the structural nature of involuntary part-time employment and its implications for labour-market inclusion and job quality in the European Union.

The project will generate evidence directly supporting EU-level policy debates on job quality, working-time arrangements and inclusive labour markets. Its findings will inform policymakers about the key structural drivers of involuntary part-time employment and the effectiveness of different institutional and policy responses across Member States. By linking empirical evidence with policy-relevant insights, the study will contribute to the design of more inclusive labour-market policies aimed at reducing involuntary part-time work and improving employment quality in the EU.
