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.

Nearly 10,000 city workers in Philadelphia are striking, disrupting trash collection, pool schedules and library hours.
