The legal fight between Illinois Governor Pat Quinn and the union that represents prisons workers continues this week.
Quinn had wanted the prisons closed by last Friday. Instead that day an arbitrator said the administration violated its contract with the prison workers' union by moving to close the facilities before they'd finished what's called "impact bargaining."
Union spokesman Anders Lindall says impact bargaining doesn't only affect employees facing layoffs.
The Illinois Department of Employment Security says it has started checking the roll of people receiving unemployment benefits for those who might be ineligible because they're in jail.
Spokesman Greg Rivara says the department found 420 people receiving benefits who were behind bars sometime during the first two weeks of the review. Now the department will check to see if they might have been only briefly locked up and were still eligible or if they really weren't available to work. Availability to work is a key part of the criteria to determine unemployment eligibility.
