Two sanitation workers who were on the picket line in the AFSCME District Council 33 union strike were hit by a vehicle in Philadelphia's Port Richmond section late Thursday night, police said. A driver is already in custody and charged with hit-and-run and driving under the influence.

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.

The AFSCME District Council 33, which represents around 9,000 municipal workers, has now gone on strike, impacting many of the city's services.
