Attention journalists preparing for next week's political conventions: Baggage handlers, security workers, and other in Philadelphia have voted to strike American Airlines during the convention — the carrier that handles 70% of the airport’s traffic, according to the Service Employees International Union (SEIU).

They have called on Democrats to support them.

“With the DNC fast-approaching, airport workers and their supporters are calling on the DNC to support their fight by demanding action by American Airlines,” the SEIU said. “American — which controls 70% of the traffic at PHL — hires and fires contractors at the airport and sets the standards for wages, benefits and worker treatment.”

The union said some 1,000 workers could walk off the job.
