Tools for Addressing Chapter Conflict by Prentis Hill
Tools for Addressing Chapter Conflict is a workbook/guidebook compiled by Prentis Hill and the BLM Healing Justice Working Group. The guidebook offers some practical steps to start thinking about conflict happening within an organization--where did it come from, what are the causes--and considerations for planning a process. Very helpful!
