A second day of negotiations between Chicago's school board and its striking public school teachers ended Tuesday with neither side expressing optimism that an agreement was near.
"This was silly season," board President David Vitale told reporters after emerging from more than 10 hours of talks. "It is time for us to get serious."
Vitale said the board had presented the union with a "comprehensive proposal" and would resume negotiating only after "we receive a written response or a comprehensive proposal of their own."
But Barbara Byrd Bennett, interim chief education officer, said the negotiating would continue Wednesday, whatever happens. "Our team will be back here tomorrow," she said.
Chicago Teachers Union Vice President Jesse Sharkey said the day's discussions had centered on teacher evaluation and that "some substantial movement" had been made, but not enough.
"I don't want to get in the weeds, but I'd say we moved more than they did today," he said.
The board proposal would leave some 28% of teachers in danger of dismissal within a two years, he said, calling that "an insult to our profession."
"They basically dug in their heels and said if we didn't give them a comprehensive proposal, we didn't have anything to talk about," Sharkey said.
The negotiations ended after thousands of striking teachers had spent much of the day massed outside the Chicago public school system's headquarters.
Carrying signs, they chanted and marched through the streets in an expression of solidarity in their fight against the school board.
