The city&#39;s teachers agreed to return to the classroom after more than a week on the picket lines, ending a spiteful stalemate with Mayor Rahm Emanuel that put teacher evaluations and job security at the center of a national debate about the future of public education. &#40;AP Photo&#47;Charles Rex Arbogast&#41; (AP Photo&#47; Charles Rex Arbogast)</span></div>
