Assign and dispatch appointments
Once work is on the schedule, this is the permission that lets you move it from one technician to another. On the Dispatch board, dragging a Work Order card to a different technician's row is a reassignment, and it needs this permission as well as permission to manage the schedule. A role that can only reschedule is told it can reschedule work for the same technician but cannot reassign it.
On a Work Order, the visit card shows the technician's arrival step for the current visit, which is the point from which work may begin. A technician can also record their own arrival while tracking their time.
Rescheduling a visit is a separate action from assigning it.
