In this Thursday, Aug. 30, 2012 photo, Emily Ponce, 8, a second-grader at Manuel Perez Jr. Elementary School, in Chicago's predominantly Hispanic Pilsen neighborhood, watches her brother Jose Ponce, 13, a Perez eighth-grader, as he talks about the chance of a teachers strike. Chicago Teachers Union President Karen Lewis said more than 26,000 teachers and support staff in the nation's third-largest school district don't want to strike, but are prepared to do so for the first time in 25 years. It would be the first big-city strike since Detroit teachers walked off the job for 16 days in 2006. The last Chicago teacher strike was in 1987 and lasted 19 days. (AP Photo/M. Spencer Green)
