By MARK KENNEDY (AP Entertainment Writer) Striking screenwriters and actors held rallies in Philadelphia and Chicago on Thursday as the labor dispute that has halted Hollywood spreads to more cities. “We have the same issues,” said Nikki Izanec, president of the Philadelphia SAG-AFTRA local, on her way to Thursday’s rally. “ And we all have a common goal, and that’s to make living wages in an industry that takes advantage of us,” said Izanec. In Los Angeles, strikers outside Netflix studios included Sarah Silverman, Aubrey Plaza, Chris Witaske and Kendrick Sampson.
