Currently supervisors have 7 – 10 employees reporting to them. With this new structure, it seems this rule will no longer apply?

That is correct. In the new staffing model we have created a tiered manager model. Management positions in Access Services that require more experience will have more direct reports. For the number of direct reports we are using FTE (full-time equivalent positions, where 1 FTE = 40 hours per week) rather than individuals.
