A strike being staged by nearly 10,000 city workers in Philadelphia has entered its second day. But a judge has ordered some emergency service dispatchers and essential water department employees to return to work.

Employees with AFSCME District Council 33, Philadelphia's largest blue-collar workers union, went on strike at 12:01 a.m. Tuesday morning after union representatives and the city failed to reach a deal.

Mayor Cherelle Parker said the city would suspend residential trash collection, close some city pools and shorten recreation center hours, but vowed to keep the city running. Police and firefighters are not on strike, but the DC33 membership includes 911 dispatchers, trash collectors, water department workers and many others.
