The CTU announced that the city&#39;s 25,000 public school teachers will walk the picket line for the first time in 25 years Monday morning after months of talks with the Chicago Board of Education failed to reach an agreement over teachers&#39; contracts by the Sunday night deadline. &#40;AP Photo&#47;Sitthixay Ditthavong&#41; <span class=meta>(AP Photo&#47; Sitthixay Ditthavong)</span>
