CHICAGO (AP) — Organizers of a Nov. 29 nationwide day of protests by hourly workers say a planned strike at O'Hare International Airport in Chicago is only a part of their push for a $15 hourly wage and union rights.

In a news release, organizers say thousands of workers plan to walk off the job at McDonald's restaurants and other fast-food spots in more than 340 cities. The planned "Day of Disruption" marks the fourth anniversary of the first protests at McDonald's restaurants in New York.

The Service Employees International Union Local 1 said Monday that hundreds of workers will strike that day at O'Hare, one of the nation's busiest airports.

O'Hare is the only airport where workers plan to strike, though organizers are planning protests at other airports.

The Chicago Department of Aviation says it doesn't anticipate any disruption in service.
