Jeff will stay engaged in the mediation process and after 3 hours (half-day), his overtime rate will apply by the hour, or part thereof.
If the mediation is booked in the morning, Jeff may not be able to stay past 1 pm if he has another half-day mediation booked for the afternoon.
If you must have the flexibility to stay past the 3 hour mediation half-day, it is recommended to reserve Jeff for the full day, or for an afternoon mediation (Jeff can usually stay late after 5 pm).
