Holiday travelers returning home after Thanksgiving may be in for a headache after it was announced that hundreds of workers plan to strike next week at one of the nation's busiest airports.

Service Employees International Union Local 1 officials said Monday they will walk off the job on Tuesday, Nov. 29, at Chicago O'Hare International Airport.

About 500 workers committed to a strike after a vote last week. The workers are trying to organize with the union's help. They work mainly for private contractors at the airport and include baggage handlers, cabin cleaners, janitors and wheelchair attendants.

The workers are seeking union rights and a $15-per-hour wage.

During a press conference Monday morning, an O'Hare employee spoke on behalf of airport workers, calling on United Airlines and other carriers to "take responsibility and stand up for good wages at O'Hare."

"We should not have to live paycheck by paycheck," the woman said, noting that she makes $11.50 an hour for a job that used to pay $22.50.

It wasn't immediately clear how such a strike would affect operations at O'Hare. The Chicago Department of Aviation has said it doesn't anticipate any disruption in service.
