Protesters stand outside Cadillac Place, Monday, Jan. 25, 2016 in Detroit, where a judge is hearing arguments in a case that could force teachers to stop skipping school. The teachers' so-called sick-outs have repeatedly forced the district to close schools during the past two weeks, keeping thousands of students at home, so in a bid to stop the absences, the district filed a lawsuit. Teachers are upset over pay, class sizes, building conditions and Gov. Rick Snyder's plan to overhaul the district. Photo: AP Photo/Carlos Osorio
