There is less a need for companies to call in temps and freelancers. http://www.reuters.com/article/domesticNews/idUSTRE56C0T120090713
It's good they're bringing the issue of legality into it. It's tough to run a consumer economy that keeps outsourcing everything, but it's even harder running a consumer economy where everyone works for free! But what a disturbing trend. Hopefully people will realize the "recession" is more than a temporary setback, it was enabled by the greed of those at the very top and won't be fixed by working for free and hoping things get better.
Some work for nothing. Most eke out a living some how. Some jobless eventually end up homeless. A decent company aught to offer these workers at least minimum wages - which isn't much. This will make it legal as well giving the "volunteers" lunch and travel money.
