Contract negotiations between Chicago Public School officials and union leaders that stretched through the weekend were expected to resume Monday.
Officials said some 140 schools would be open between 8:30 a.m. and 12:30 p.m. so the children who rely on free meals provided by the school district can eat breakfast and lunch, school district officials said.
City officials acknowledged that children left unsupervised — especially in neighborhoods with a history of gang violence — might be at risk, but vowed to protect the students' safety.
"We will make sure our kids are safe, we will see our way through these issues and our kids will be back in the classroom where they belong," said Emanuel, President Barack Obama's former chief of staff.
The school district asked community organizations to provide additional programs for students, and a number of churches, libraries and other groups plan to offer day camps and other activities.
Police Chief Garry McCarthy said he would take officers off desk duty and deploy them to deal with any teachers' protests as well as the thousands of students who could be roaming the streets.
Union leaders and district officials were not far apart in their negotiations on compensation, Chicago Teachers Union President Karen Lewis said. But other issues — including potential changes to health benefits and a new teacher evaluation system based partly on students' standardized test scores — remained unresolved, she said.
