The Community Building Sphere also serves staff, volunteers, and others who are involved in the RJ Network. It offers preventive care by providing training for those who work with parties to crime. This training includes anticipating and recognizing the indirect harm of crime on themselves. It also provides opportunities for role changes within the Community Building Sphere, and sabbaticals on regular bases.

The Community Building Sphere also provides assistance to staff members needing it. For example, support staff working with parties involved in a severely traumatic event will have access to other support staff for debriefing and reflection. In the event that staff members suffer physical harm while they were working, volunteering, or interning for the Hub, medical care is provided. If staff members need psychological care because of their working, volunteering, or interning for the Hub, such assistance is provided. Those staff members who seek religious or moral care because of an event that happened while they were working or volunteering for the Hub are provided it.
