An example system for dynamic agent management involving multiple queues is presented. The system may include a remote network management platform that manages a network by way of a computational instance. A first group and a second group of agents may be assigned to address work items in a first queue in the computational instance. The second group may also be assigned to address and prioritize work items in a second queue in the computational instance. A computing device within the computational instance may assign a work item originating from a client device in the managed network into the first queue according to routing rules. The assignment may cause a timer to record a duration that the work item is in the first queue. The computing device may assign one of the second group of agents to address the work item based on the duration exceeding a pre-determined value.
