Many are McDonald's employees who say they deserve more than the minimum wage.
"I'm frustrated. I'm a hard worker, I'm dedicated. And I cry my heart out to my employer every day saying, can I get a raise, can I get a raise, I need a raise," said Tyree Johnson, protester.
It is the latest in a series of demonstrations organized by fast food workers across the nation. Dozens of employees walked off the job in strikes in Chicago, Detroit, Milwaukee and St. Louis in recent weeks to demand their wages are increased from $8.25 an hour to $15 an hour. They have labeled their cause the "Fight for 15."
The Chicago workers went on strike on April 24. On Thursday morning, they plan to board buses to McDonald's headquarters in Oak Brook to deliver a petition at the company's annual shareholder meeting.
