Fast-food workers walked off their jobs in dozens of cities Thursday, demanding a $15-an-hour minimum wage.
Union organizers say the strikes will reach 150 U.S. cities and several countries.
CNNMoney confirmed that workers were striking at a McDonald's in Trafalgar Square in London.
"I am proud that I am striking and I am trying to get a better life," Rosa said. "I am fighting for everyone in fast food."
