CHICAGO (AP) — Hundreds of O’Hare International Airport workers have voted to go on strike ahead of the Thanksgiving holiday.

Officials with the Service Employees International Union Local 1 said Thursday that about 500 workers have committed to strike. Union spokeswoman Izabela Miltko-Ivkovich says the strike “will definitely take place in the coming days,” though she didn’t specify which day it will start.

It wasn’t immediately clear how such a strike would affect operations at O’Hare, which is one of the nation’s busiest airports. Auto club AAA predicts it will be an especially busy Thanksgiving weekend of traveling.

The workers who plan to strike include baggage handlers, cabin cleaners, janitors and wheelchair attendants. They are seeking a $15 wage.
