"So I will not get tax credits or a full refund from PA and the city of philly because its not "required" by my employer that I work remotely?"
Yes, that's correct. PA state law was cited earlier in this thread; here's a link to the City of Philadelphia's stance on the issue:

It's interesting, and seemingly contradictory, that PA specifically does not require Pennsylvania employers to withhold PA income taxes from the pay of PA non-residents unless they perform work within PA. See page 1 of the PA employer withholding guide here:
