Years into the recession, millions of America’s workers remain unemployed or underemployed, even as U.S. corporations are sitting on trillions of dollars in cash, refusing to create jobs. The share of unemployed workers who have been jobless for more than six months shot up from 17.6 percent in the first half of 2007 to more than 45.6 percent by spring 2010, and it remains near that percentage today. For millions of jobless workers, unemployment insurance (UI) is their only lifeline. Yet each time Congress considers extending (UI), Republicans and some Democrats seek to block it, delaying badly-needed support for hard-working families who for years paid into the unemployment insurance system.
