The Chicago Teachers Union has a new leadership team.
She's joined by new Vice-President Jesse Sharkey, Recording Secretary Michael Brunson and Financial Secretary Kristine Mayle.
The new team beat the United Progressive Caucus team led by two-term CTA President Marilyn Stewart, according to a release from the CTU.
Lewis garnered 12,080 votes, while Stewart had 8,326.
Stewart released a statement Saturday congratulating Lewis on her victory and assuring her cooperation and assistance through the transition.
"This election was never about Karen or me. It was about the 32,000 union members whose futures and well-being are now being threatened by an uncaring and insensitive Chicago Public Schools system. A system that thinks it can balance its budget on the backs of this city’s teachers and students. A system that thinks stuffing 35 students into a classroom and cutting teachers’ pay is the answer to their problems."
Stewart asked "all members of this union -- those who voted for me as well as those who didn’t -- to stand behind Karen and her team and support them as they take over the fight in your behalf."
The CTU earlier this week sued Chicago Public Schools over its decision to increase classroom sizes.
