Report: Poverty and the Rise of Temporary and Contingent Work

The nature of employment is changing. Employees are increasingly seen as liabilities rather than assets, and so workers are kept at arm's length from the companies they ultimately serve. Middle-class long-term jobs are shifting to precarious, low-wage work. These contingent relationships include temporary and subcontracted workers, whose ranks have been growing over the past two decades.

In California almost one-quarter of a million people worked in the temporary help services industry in 2010; another 37,000 people worked for employee leasing firms totaling 282,000 workers in these two industries. This accounted for approximately 2.0 percent of all non-farm employment in California in 2010, approximately the same ratio as for the U.S. as whole.
