This article: Restorative Justice and Social Work links the core values of social workers to Restorative Justice Practice.
It is from 2002, but I really appreciate how well written it is.
I used to work for Amicus, and it makes me proud the author lists it as an impressive program.
I found this gem on a website I have been spending a lot of time on: http://www.restorativejustice.org.uk/ You should check it out! Best Practices, stories, research!
