Procedure
During final approach to ILS PRM 10C in ORD; constant taxi instructions were being given to preceding aircraft upon landing. The monitor frequency is supposed to be a SAFETY FREQUENCY for transgressions or proximity of aircraft; not a supplementary taxi frequency because the south tower is short staffed and the Monitor is the ad hoc taxi controller.
Air Carrier Captain reported Tower was giving taxi instructions on the PRM Monitor frequency.
