One of the reasons you need more managers is because so many "services" have been farmed out to private companies, who need to be monitored, changed, have contracts drawn up, tout for the cheapest etc. A mammoth task.
I am not manager bashing, but I do have experience of the NHS before all this started, when hospitals were institutions with clear aims and clear lines of responsibility. When, if something was amiss, you could speak to the person responsible and something would happen. When everyone from cleaner to consultant was pulling together as a team. The whole ethos was a shared desire to do the best for the patient.
The fragmented service we have now leads to the need for more management. It is mad, and stems from political dogma - the idea that farming services out leads to money-saving via competition is nonsense. It leads to more work for the managers, who have to be paid. It leads to complex structures. And very very poor communication.
I have the most vivid memory of the changeover to outsourcing. One of the corridors had a long brown stain all the way along it - it was probably dried blood. No-one took responsibility for getting rid of it. There was no clear line of responsibility; no-one among the outsourced cleaning service dealt with it (it was probably not scheduled for cleaning that day) - no doubt the appropriate hospital manager was contacted (or left a message if out at a meeting) who then would contact the cleaning company in their far-away office and that communication had to make its way past various people in their organisation and back through the hospital management system - it certainly did not get as far as the corridor!
Before, whoever had seen it first, or seen it happen, would have knocked on the door of the cleaning team and they would have arrived within minutes. Job done!
