Food service and hospitality workers will rally at Philadelphia International Airport at 9:30 a.m. Monday and later join a march at City Hall at noon organized by Juntos, an immigrant rights group. Monday is International Workers' Day, and the union Unite Here is sponsoring rallies in 27 cities to call attention to poor wages and working conditions and the Trump administration's "anti-worker" policies.

Most employers at Philadelphia airport, either through union contracts or city lease requirements, now pay the city's minimum $12.10 an hour wage, but "there are a few outliers," said Unite Here Philadelphia Local 274 president Rosslyn Wuchinich. The mostly-immigrant workforce at LSG SkyChefs, an airline catering company that provides meals for many flights, still earn as little as $7.90 an hour and work in difficult conditions, Unite Here said. "At least 50 hospitality workers, many of them airport workers, are taking Monday without pay to participate in the day of action," Wuchinich said.
