Over the last decade cyberbullying has become a global issue affecting more and more young people. With the increased use of mobile technologies and permanent online access more young people have become involved in cyberbullying as victims, perpetrators and/or bystanders. The European Commission defines cyberbullying as repeated verbal or psychological harassment carried out by an individual or group against others by means of online services and mobile phones. According to recent data, in Europe more than 50% of children bullied online said that they became depressed as a result and over a third of them stated that they harmed themselves or thought about suicide (Cyberbullying among Young People report, 2016). The EU institutions have recognized the dangers posed by cyberbullying. However, despite the commitment of the EU institutions to tackle cyberbullying there is no specific EU law on cyberbullying. EU actions have been limited due to the fact that the EU has a limited competence in this area which falls within the remit of the Member States. From the other side, tackling cyberbullying presents two main challenges. Firstly, the internet offers anonymity and a sense of impunity to perpetrators, and aggravates the victimization, as the harmful content is spread instantly to a far wider audience; and secondly, one problem with cyberbullying is that information remains online for a long time and can be difficult to remove even if new EU data protection rules introduced a ‘right to be forgotten’ that allows victims to request the erasure of their personal data. In this scenario, youth workers have a role to play because for their proximity to young people they can educate them about cyberbullying, its effects, and the importance of ethical online conduct. It is therefore more important than ever that youth workers develop their own competences and educate themselves about where and how cyberbullying occurs, the role of the web, and how to prevent cyberbullying. Having all this in mind, “Stay safe in cyber space” project will provide youth workers with new knowledge and competences on cyberbullying.
