Abstract: A method and system for matching a knowledge worker to a selecting entity's needs according to a system of codes corresponding to pre-defined rules of engagement. The rules of engagement include, but are not limited to, experience levels, salary, geographic location, job starting date and duration, and industry sector. If a search of knowledge workers fails to match an available worker with a job need of the selecting entity, the selecting entity posts a job posting on a website maintained by a third party administrator who maintains webpages that are accessible only to screened job applicants.
