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.

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

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