There was a sad story in December about the case of a 10 year old boy who had been suffering from four years of bullying at school, which was so severe that it ended up putting him in hospital several times due to injuries and anxiety.
In the end, rather than dealing with the perpetrators, the school ended up sending the victim to a different school. Problem solved, right? Except perhaps for the poor kid that is on the next rung up on the totem pole.
This is still pretty typical for Spain. There isn’t really the recognition of the psychological aspects of bullying, and the burden of proof for victims is very high. There are a couple schools in Barcelona with good anti-bullying practices, such as the American School of Barcelona.
