"Contingent workers---including part-timers, free-lancers, and contractors--- consistently make up about 30 percent of the [American] workforce between 1996 and 2005. . . [and] . . . that number may be higher next time they measure."
--- That's from a Newsweek article by Linda Stern.
(The article is from January, 2009, but my feeling is that not much has changed, jobs-wise . . . at least not for the better.)
In the article, you'll find mentions of "elance.com, a job-auction web site," snagajob.com, and Freelancers Union.
One bit, particularly relevant here: " . . . highly qualified workers who aren't good at the business side of selling themselves, over and over, can suffer."
