Hi jackslad
We usually hear on the forum that decision are taking 8 weeks after an assessment, I would contact DWP to see what is happening with your decision, at the same time request a copy of the assessors report called a PA4.
I doubt that PIP will be waiting for your WCA, sometimes PIP will use an existing WCA claim to help clarify a claim.
