Nowadays, electronic devices are not only the work tools of adults, phones, tablets and laptops also play an important role in the everyday life of young people: they regularly play online games, chat with friends or just get information on the Internet. Nowadays, young people do not communicate face-to-face, personally, but keep in touch with each other through online platforms. They use online platforms to talk to each other, and about each other. On these platforms, communicating in this way, hurting and harassing each other spreads more and more in the absence of control. Along with the spread of social media and electronic devices, cyber bullying also appeared and became an increasingly frequent threat. Cyberbullying is characterized by the use of digital technologies with the intention of hurting, humiliating, threatening, harassing or abusing someone. We distinguish different types, but these are the characteristics of each type. As the Internet and electronic devices have become an inevitable part of young people's lives, it is the responsibility of adults to help young people become responsible digital citizens who can use the Internet and social media appropriately. There are many difficulties in preventing and dealing with cyberbullying. Young people use the Internet without supervision, parents cannot influence their child's online behavior due to technical difficulties. It is also difficult to count on the help of teachers, cyberbullying typically takes place after school hours. Victims often remain silent about the harassment, and witnesses do not speak about it either, fearing that they themselves will become a target. Preventing cyberbullying is a complex task that requires cooperation and effort from young people, parents, teachers, institutes, legislators and social media. Educational and attention-grabbing media campaigns, school programs, parental supervision that can intervene if necessary, and legislative activity can be successfully applied. Various instructors, youth workers, and mentors can also help. The goal of the project was to enable youth workers to prevent cyberbullying, recognize it during cyberbullying, and intervene appropriately. As a result of the project, youth workers became able to intervene in the early stages of cyberbullying and support the victim in an appropriate way. In addition, they learned methods and good practices that can be used to teach young people how to prevent cyberbullying and how to fight against it. The youth workers acquire competence, learn different techniques and methods, with the help of which they will be able to help the victims individually. By the end of the training, the youth workers were able to draw the attention of parents, teachers and decision-makers to the importance of the topic. The main target group of the project was youth workers who are able to actively help victims of cyberbullying and understand the motivation of bullies. The impact of the project on young people is also significant, as they can be victims, witnesses, or even perpetrators of cyberbullying. Parents, teachers, and decision-makers are also affected, for them in many cases cyberbullying is an unknown concept, so they are unable to recognize or deal with the problem. The basic values of Erasmus+ also appear among the project's goals, such as mobility, capacity expansion, and increasing social sensitivity. The premature leaving of school by young people is a significant problem in our society, and the project provides assistance in this regard as well.
