She’s just a common thief, “kicking the NHS” doesn’t come into it.
If you want to see how the government is kicking the NHS, read this part of your link:
”The NMC report added that if the fraud had not been spotted, the trust would have lost £31,577.31, working on average of just over £410 per shift charged by the agency.”
£410 per shift
Let that sink in. There’s a place flexible bank staff, both from the NHS wanting that and the agency worker.
But a system where that’s costing £410 (mostly into the pocket of the agency) is disgraceful.
