We’ll the link did seem to suggest tens of thousands of EU citizens working in the NHS. Given the raw deal the NHS has had during COVID, and seems likely to get in the next few years, I’d not be surprised to see the non-settled EU staff (ie, the ones without family commitments here) buggering off in their droves. The numbers leaving the register have already increased by a factor of 75%, and where that number used to be fairly dynamic (ie, 4000 left in any given year while a similar number joined) I don’t see any inward EU migration to the NHS at the moment, and see no reason to expect it to pick up again.
