PHILADELPHIA (CBS) — Nearly 1,000 workers at Philadelphia International Airport are preparing to walk off the job during the Democratic National Convention.

The workers handle baggage, clean airplanes, and help travelers in a number of ways. They voted overwhelmingly to strike, but no exact date was set.

SEIU32BJ Vice President Gabe Morgan says striking during the Democratic National Convention was done with a purpose.

“Fifteen dollars an hour is a plank in the DNC. It was huge subject of debate during the Democratic Primary, and really what these workers are fighting for is the same thing the DNC is fighting for in the upcoming national election.”

They also hope to gain better working conditions and the ability to unionize.

Mayor Jim Kenney released the following statement regarding the strike on Friday night:

“Governor Wolf and I have brought 32BJ SEIU and American Airlines together to come to an agreement that will give employees of airline vendors the opportunity to form a union of their choosing. Beginning today and into next week, 32BJ and American will be working together on such an agreement and to ensure the smooth operation of the Airport as thousands of delegates from around the country convene for the Democratic National Convention. I look forward to a resolution that works for all parties and ensures the highest level of service at PHL. I would also like to commend Congressman Brady and Councilman Henon for their invaluable efforts in making this progress possible.”
