Illinois Gov. Pat Quinn wants to negotiate with unions to keep labor reforms at Chicago's McCormick Place convention center.
But he also says he and top lawmakers are ready to bring legislators back to Springfield in September to fine tune any necessary legislation.
Quinn met Tuesday with Mayor Rahm Emanuel and the state's four legislative leaders about ways to keep the work rule changes.
A federal judge ruled in March that many of the labor reforms lawmakers wanted at McCormick were illegal because they went beyond the terms of union contracts.
The judge also ruled legislators overturned collective bargaining rights in violation of the National Labor Relations Act.
Some conventions have pulled out of the city because of the high cost to host events at McCormick.
