The struggle for living wages continues today with two metro-area events. In the first, airport workers will rally at National Airport at noon to announce plans to hold a strike vote over the holiday season to demand $15 an hour. Then at 6:30p, more than a dozen organizations and local officials will gather for a vigil at the Montgomery County Council Office Building to support the passage of a $15-an-hour minimum-wage bill. The rally and vigil are part of a national day of action for low-paid workers on the fourth anniversary of the first worker strike for a minimum wage above the federal minimum wage. Workers at DCA and Dulles have reported that they can’t afford rent or transportation to and from work, while others lack time to go home between shifts and other jobs.
