Occupancy rate measures how much of a human agent's shift is spent talking to customers, versus sitting between calls. The target in most call centers is 80 to 85 percent. Higher than that and the agents burn out; lower and the cost per interaction climbs.
The metric only makes sense for humans. AI agents are either handling a conversation or not, and the cost of an idle agent is zero rather than the loaded hourly rate of a person sitting at a desk. Applying occupancy targets to an AI tier of the operation is a category error.
In a hybrid operation, occupancy still matters for the human team. A well-designed AI layer absorbs the routine volume and concentrates the harder cases for the humans, which can drive human occupancy up. A poorly-designed layer leaves the humans handling spillover at random times, which makes occupancy harder to plan against, not easier.
Vorel reports human-team occupancy alongside AI volume in the operator console, so the manager can see whether the AI tier is smoothing the human workload or making it spikier.
