One of the largest efforts to help Veterans find employment returns to Chicago March 28 in the second annual Hire our Heroes career expo. The U.S. Chamber of Commerce, Chicagoland Chamber of Commerce and the Illinois Department of Employment Security are primary sponsors. More than 100 Chicago-area businesses, many with outlets throughout the state and Midwest, have positions ready to be filled. Veterans should dress appropriately, bring resumes and be prepared for a brief, preliminary interview. Civilians also are invited. The expo is from 9 a.m. to 1 p.m. at The Hilton Chicago, 720 S. Michigan Avenue. Veterans and others seeking work can pre-register at www.uschamber.com.
