Embodiments of the present invention address deficiencies of the art in respect to queued requests to establish human-to-human collaborative sessions and provide a novel and non-obvious method, system and computer program product for managing queued requests to establish human-to-human collaborative sessions. In one embodiment, a human-to-human collaborative data processing system can be provided which can include a messenger configured for coupling to other messengers. The system further can include a queue of incoming session requests to establish respective human-to-human collaborative sessions with requesters associated with the other messengers. Finally, the system can include queue management logic enabled to order the session requests in the queue according to queue rules coupled to the queue management logic.
