Chicago organizations that offer after-school and weekend youth programs are scrambling to accommodate children during weekdays as the city’s teachers walk the picket line, NPR reports.

The Chicago Boys and Girls Clubs, the YMCA, and other groups are bringing in additional volunteers and even senior management staff to meet the daytime influx as working parents scramble to find safe places to leave their children. Food banks and churches are helping to replace breakfasts and lunches kids would normally get at school.

Some 350,000 students have been affected by the teachers’ strike in the country’s third-largest school district, which began Monday.
