The project 'C4C: Communication for cooperation – Next Chapter' was developed with an aim to empower youth workers through a set of key communication skills in order to facilitate and spread tolerance in the European youth sector. The project consisted of three stages: preparatory arrangements, training course and follow up activities. The main activity was the training course tackling the development communication skills, which took place in Slovenia in Ajdovščina. The main activity took place in Ajdovščina, Slovenia, where 22 people (18 participants + support team) gathered to experience an intense 6-day training course. Topics covered were: nonviolent communication, transaction analysis, giving feedback, mediation, public speaking, assertive communication, ICT tools for communication and the role of communication skills in the context of youth work. The participants were all active youth workers, facilitators and educators from the partner countries Slovenia, Italy, Portugal, Spain, Latvia, Finland, Romania, Cyprus and the Netherlands. The main objective of this project was to equip participants of the TC to become ambassadors of tolerant dialogue and to raise awareness on the importance of communication skills and tolerance in the light of the changing European society. Specific goals of this project were: G1. To gain the knowledge about different forms, strategies, norms and mistakes of communication. G2. To gain practical skills of communication to be used in working with diversity and inclusion G3. To experience the barriers of cooperation and learn the strategies to cope with them in daily life G4. To gain skills of specific communication methods, such as feedback, mediation, nonviolent communication, mediation, transactional analysis and public speaking G5. To acquire skills of ICT tools for communication and trigger discussion on media literacy and critical thinking G6. To plan and implement at least one follow up session about communication for cooperation in each partner country G7. To produce various forms of dissemination material The main project activity enabled participants to learn about new aspects in terms of communication that changed their perspective on human communication and gave them a fresh view on the topic. They have strengthened their skills, know-how and competence in terms of communication and improved their employability chances in the labor market.The participants were genuinely interested in the project topics and have prepared detailed plans on how to transfer this know-how to their local environments, present it to young people in their home countries. This phase was rather successful which led to the project contributing to the spreading the skills of tolerant communication into 9 different countries. We are pleased that the project topic attracted people, eager to learn and improve and we hope to have given them useful tools which will help them deal with communication challenges, conflicts and support them in creating a European culture of peace, tolerance and mutual understanding.
