Transportation department spokeswoman Paris Ervin says personnel manager Scott Doubet was fired Friday. Doubet was among 12 department employees who received what Gov. Pat Quinn has called "midnight raises" weeks before Blagojevich was removed from office over corruption allegations.
Doubet's salary was $55,000 in 2004 but reached $106,000 this year.
Quinn has launched an investigation into the raises. His spokesman Bob Reed would not comment on the firing.
Doubet declined to comment Friday and said he does not have an attorney. He has not been accused of wrongdoing.
