The Illinois changes apply only to new employees, but business leaders say the state can't afford to pay benefits at current levels and are pushing for cuts.
"The reform did not fix the problem. It's very significant in the changes it makes for employees not yet hired, but the state faces an immediate crisis in figuring how it is going to fund current employees' benefits," said Laurence Msall, president of the Chicago Civic Foundation, a business watchdog group.
In Houston, Milwaukee County, and San Diego, city officials were able to get rid of DROP for new employees only.
