Negotiations are back on between DC 33 and the City of Philadelphia as the city's largest strike in nearly 40 years continues.

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.

Striking city workers are joining picket lines outside Philadelphia City Hall, public libraries and other worksites as nearly 10,000 unionized employees walked off the job in search of better pay and benefits.
