They're frustrated that Illinois has gone nearly two weeks without a budget. Lawmakers are due back in Springfield Tuesday to work on a deal.
Without a budget, checks could be delayed for state employees and groups that provide services on behalf of the state.

"It's not about public employee unions, it's about providing services. When you're going to lay off 1,000, 2,000, prison guards, you're talking about devastating communities down state," said Larry Spivack, an AFSCME regional director.
State Representative D'Amico was not able to be reached for comment.
