The city ordinance also would provide some job protection for 1,500 concession workers at O'Hare International Airport if new contractors take over the concessions.
Ald. Ricardo Munoz, 22nd, said it's unreasonable that some restaurants at the airports sell hamburgers and beers that cost more than an hour's wages for the workers who prepare them.
If the cost goes up for food and other items sold in the concourses, so be it, said Munoz, who is running for re-election Feb. 22.
If a new contractor takes over concessions, existing workers would be allowed to keep their jobs for at least 90 days, unless an employer had cause to fire them. Those who were laid off after 90 days would be put on a rehire list, with the first chance to get their jobs back.
Jeff Grays said he makes $8.50 an hour working for Hudson News at O'Hare. "If we get this living wage set in, I could take better care of my family, give them a reason to look up to me," Grays said.
