This is an added service for practices, when they are unable to find locum cover via the locum availability system, they can place a requirement that all GPs in the network can see. In your view, this is a combined list of all such placements. If there are none, it simply means that practices have no requirements they cannot match using the main system. Sometimes this may have 3 or 4 requirements in it. When such a requirement is created by a practice the system sends an email out to all GPs to let them know.
