All but three of Detroit's public schools are now closed for the day amid a sick-out by teachers protesting funding issues at the financially struggling district.

District spokeswoman Michelle Zdrodowski said in an email early Monday that 94 of the district's 97 schools have been closed for the day. About 46,000 students are enrolled in the district's schools.

The Detroit Federation of Teachers on Sunday urged its members to call out sick following an announcement that the district wouldn't have enough money to continue paying teachers this summer, or funding summer school or special education programs, without further state funding.

The governor approved emergency funding to keep the district running in March, as lawmakers consider a $720 million restructuring plan to pay off the district's enormous debt.

Former bankruptcy Judge Steven Rhodes was appointed this year to oversee the district. He said Sunday that a sickout was "counterproductive and detrimental" to the efforts of those trying to help the school district.
