Chicago Teachers Union President Karen Lewis said Friday evening she is disappointed with the latest offer from the school district and that the two sides will resume negotiations Saturday.
She said the union was hoping to get a proposal that would answer the member's concerns, but did not. Both union and district officials said earlier Friday they were optimistic about the talks.
Union and district officials have said they will negotiate through the weekend, if necessary, to avoid a Monday strike. Teachers are threatening to walk off the job for the first time in 25 years over issues that include pay raises, job security and teacher evaluations.
There also is a lot at stake for Mayor Rahm Emanuel, who has made school improvement a central theme of his administration.
