Mayor Rahm Emanuel will begin his next term without one of his top aides.
Lisa Schrader has been both chief of staff and chief operating officer during Emanuel's first term. Before that, she worked for former Mayor Richard Daley's administration for a decade.
Schrader is leaving the administration next month to follow opportunities in the private sector, the mayor's office announced in a Monday statement.
Emanuel said he's sorry to see Schrader go, adding she was reliable during her time in his administration. Schrader said in the same statement that it's been an honor to work for the city. She said she's ready for a new chapter.
Emanuel won a second term earlier this month after beating Cook County Commissioner Jesus "Chuy'' Garcia in Chicago's first mayoral runoff election.
