When McDonald’s opened its 86-acre campus in Oakbrook in 1971, Chicagoans were moving from the city to the suburbs. Now the fast-food giant is planning a big move to Fulton Market in Chicago next year, signaling a larger trend of companies making a trek closer to or in the city limits — leaving suburban workers with a longer commute or no job at all.

McDonald’s announced its move last year, saying it would bring about 2,000 employees to Fulton Market in a building that is currently under construction.

Other companies are making a big move to the city, according to the Chicago Tribune. Kraft Heinz, farming supplier ADM, and Motorola Solutions are moving to Chicago. Machinery business Caterpillar announced earlier this year that its headquarters would move from Peoria to Deerfield, closer to Chicago, leaving just 12,000 manufacturing jobs in its original hometown.

 The trend of suburban companies moving to urban locations is largely driven by the workforce and shift in the influence of technology. Because IT operations and technology divisions are of growing importance, companies are making sure that they are near young, tech-savvy professionals.

"It used to be the IT division was in a back office somewhere," Mayor Rahm Emanuel told the Chicago Tribune. "The IT division and software, computer and data mining [operations], et cetera, is now next to the CEO. Otherwise, that company is gone."

McDonald’s wooded Oakbrook campus, on-site Hyatt hotel, Hamburger University training center, and 8-story office building are up for grabs. Located just east of the Oakbrook Center mall, the location is ideal — for someone else. While future of the McDonald’s campus is unclear, developers believe the space will be better suited for residential or retail conversion instead of remaining an office property.
