Hundreds of workers and their supporters protested in front of Philadelphia International airport Tuesday, in a fight for better pay and benefits.

The demonstration outside of Terminal A included baggage handlers, cabin cleaners and wheelchair attendants who work for PrimeFlight Prospect and McGinn Security. They carried a sign which read, Respect Black Workers.

They also argue that the airport workforce is made up primarily of African-Americans and African immigrants who "live in poverty," according to a news release organizers issued before the protest.

"Last year alone the airlines raked in more than $23 billion in profits. Meanwhile, Philadelphia remains the worst city for deep poverty in America—with black Philadelphians twice as likely to live in poverty as whites," according to the Service Employees International Union.[[387480331,C]]
