After years of experience in detention visiting, the JRS Europe network decided that it was time to gather the observations and expertise acquired in one book. And the best way to pass on that knowledge to new team members starting out as detention visitors is to present it in the form of a manual, including exercises and encouragement to real learning. Being a detention visitor means to work within a multicultural environment, with people in distress. JRS has produced this manual for new detention visitors as a tool to help them and in particular new detention visitors to work in such a difficult environment. The first chapter deals with intercultural differences and intercultural communication; the second chapter provides psycho-social support to detainees; and the third chapter presents the international detention legal framework and advocacy issues.
