Philadelphia's largest city workers' union is going on strike for the first time in nearly 40 years on Tuesday after a deal couldn't be reached with the city. AFSCME District Council 33, which represents thousands of city workers, is walking off the job after negotiations didn't end in a deal. The union last went on a strike in 1986.

Many AFSCME DC 33 members have been itching for the union to take a dramatic stand against the city ever since then-Mayor Rendell won concessions in a 1992 contract. On Tuesday, they got their wish.
