A strike by nearly 10,000 city workers in Philadelphia has stretched into a third day. Trash continued to pile up Thursday in some areas, and a judge ordered more than 30 Medical Examiner’s Office staffers back to work because of a growing backlog of bodies in storage.

While police and firefighters are not on strike, many of the city's blue-collar workers, such as trash collectors, are, according to Reuters.

Sanitation workers in Philadelphia could go on strike as soon as Tuesday, stopping regular residential trash pickup in the city.
