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.

AFSCME District Council 33 represents 9,000 employees ranging from sanitation workers to crossing guards. Trash pick-up, pools and 911 calls are among the services impacted.

The strike by thousands of blue-collar Philadelphia city workers entered its second day on Wednesday, and the walkout is already having a visible impact.
