Chester Upland teachers and support staff have voted to keep working even though they might not get paid.
The district, which is under state control, serves about 3,800 students and is due to open next week.
The teachers have been told the district could not make its Sept. 9 payroll after a Delaware County judge rejected the district's financial recovery plan. At issue is how the district would pay its debt even if certain charter school payments are reduced.
Chester Upland said in January 2012 that it couldn't afford to pay its employees, but the state used emergency funds to keep the schools open.
