It's a partnership between BOMA/Chicago, the City of Chicago, and World Business Chicago.
Michael Fassnacht, President and CEO of World Business Chicago, joined ABC7 Eyewitness News at 7 p.m. to talk about what's in store this week.
To engage workers and help encourage people to return to working from the office at least a few days a week, Chicago Returns will announce free giveaways to people who come into the office May 2-6.
The prizes include an array of activities, gift cards and cash that any Chicago worker can become eligible for by uploading a photo on social media and tagging or hashtagging @chicagoreturns or #chicagoreturns between May 2-6.
Each day, several winners will be drawn for cash prizes up to $1,500, restaurant gift cards, and even a month of free parking.
