An interesting approach of dealing with bullying problems in schools is the so-called support group approach. English solution-focused practitioner Sue Young writes: "The approach addresses bullying by forming a support group of ‘bullies’ and/or bystanders. Without apportioning blame, it uses a problem-solving approach, giving responsibility to the group to solve the problem and to report back at a subsequent review meeting." As you can see this is very solution-focused approach because no blame is used, and causes of the bullying are not investigated. Instead, the collaborative solution-building process starts right away. If you're interested you can read more in this article: Should We Blame the Bullies?
