Both PMDL and PMNW FAs don't get paid until unless they fly. The scheduling mess up at worst meant that one group of people was going to have an unpaid vacation day at the airport. Best case fly a bunch of reserve flights and hope you're not out of position for the rest of your schedule. Even in that case it would mean that the reserve FAs would lose out on pay, but they would never really know.

Which crew ended up flying? I'm guessing it was the PMNW crew since they actually have a labor contract.
