Here's an analogy for you.It's important to keep the NHS public, however, the NHS needs full restructuring.
A former NHS manager tells me that before she left 2 years ago, in her trust 50% of the employees where non patient facing...50%!!!
Don't know how true that is, but even 25% sounds like too much to me.
Bob is a tyre fitter. He's been one for 30 years.
When he first started in the game, he would complete the entire process by himself. Drive car into service bay, remove the wheel, remove the defective tyre, take a new tyre off the shelf, fit the new tyre to the wheel, balance it, put it back on the vehicle, drive the vehicle out the service bay, take payment from the customer.
Bob is due to retire. He'll be missed by his colleagues, colleagues that have gradually joined him over his 30 years.
Service bay vehicle access technician (they ensure Bob drives the vehicle into the bay in accordance with current legislation).
Wheel removal compliance officer (they ensure Bob removes the wheel in a manner that isn't detrimental to the vehicle).
Tyre removal compliance officer (they ensure Bob removes the tyre safely).
Tyre retrieval technician (they get a new tyre for Bob off the shelf and ensure it is safely delivered to him).
Tyre to wheel attachment technician (they ensure Bob is fitting the new tyre correctly).
Wheel balance adviser (they advise Bob on correct wheel balance procedure).
Wheel reattachment compliance officer (they ensure the wheel is reattached to the vehicle correctly).
Payment adviser (they ensure Bob has taken payment in accordance with the company's financial instructions).
Bob recalls the days when he often worked in the service area on his own, however he'll miss some of the 8 colleagues that now work alongside him.
In some but not all cases, that's the NHS.
