Our aim is to show how digital skills training for school social workers in Poland became possible with the involvement of human rights activists, media, intellectuals and human rights trainers. School social work in Poland has become the focus of activity for trainers focused on human rights. The huge training process began in response to the need for hate speech prevention which was first expressed in Polish intellectual circles and mainstream media. It led to the school social work development programme, based on the metaphor of garden and gardening within the hate speech prevention discourse. We describe action research focused on our way of teaching school social workers to be the gardeners of the internet space.
