Given the fast pace of technological change today, many organizations find themselves facing problems and opportunities they've never faced before. This means that they need workers with highly specialized skills on short notice to deal with an issue or complete a temporary project initiative.
Some of the reasons that highly skilled or focused workers tend not to seek full-time jobs:
It’s now easier than ever through social networks such as LinkedIn and Google+ for you to build networks and keep in touch with your organization’s community of past and present contract workers. This means it is easier than ever to do your own recruiting, or reconnect and reengage with someone you’ve worked with in the past.
This means that for many engagements, there is no need for a recruiter, and senior managers can do it themselves, thereby saving time and eliminating recruiting fees.
If this describes your reality, direct sourcing may be the best way for you to get the results that you're looking for.
