Fast food workers walk off the job over money, union rights

Thousands of workers at McDonald's restaurants around Chicago walked off the job over union rights and an hourly wage of $15.

The strike is part of a nationwide campaign for more money at fast-food restaurants. Similar protests were expected in New York and Boston.

About 500 workers at Chicago's O'Hare International Airport also committed to the strike on Tuesday. They include cabin cleaners, janitors, wheelchair attendants and baggage handlers.

The workers are employed by private contractors. Strike organizers say many work for minimum wage. They're trying to unionize with the help of Service Employees International Union Local 1.

Organizers say they expect delays and disruption, particularly for American and United Airlines, but Chicago Department of Aviation officials say they don't anticipate disruptions.
