DETROIT (AP) — Nearly all of Detroit's public schools were closed Monday and more than 45,000 students missed classes after about half the district's teachers called out sick to protest the possibility that some of them won't get paid over the summer if the struggling district runs out of cash. The move by the Detroit Federation of Teachers came after Detroit Public Schools' transition manager said the district would have no money to continue paying teachers this summer without further funding from the state. The state had approved $47.8 million in emergency money in March to keep the 46,000-student school system operating, but that amount only pays the district's bills through June 30. Detroit Schools also would be unable to fund summer school or special education programs after June 30. The state Legislature is considering a $720 million restructuring plan that would pay off the district's enormous debt. Parkman, 42, was able to get his mother to watch the kids Monday, but said he might have to take time off from his catering business if more sick-outs are held.
