My store was in a similar situation last year. We lost our DTL, GVP, and RVP within the span of a month. Technically, my district's STLs were reporting to Tina. In reality, we had a DTL from a neighboring district in the area for a day or two about once every couple of weeks. The STLs reported to them until we got a new DTL. But even now, my district gets a lot of visits from the DTL and the Group team.
