Maisie, I thought he was saying that the government sees people working for the state as those who could be working in our vacant jobs. If that is the expectation, I would question it, although nothing surprises me these days. As an example of government/management thinking, it would be irrational. Why would you want a Data Analyst, for example, someone vetted to do that job and with high-level skills in that area, to drive a truck, or pick fruit?
We do see, however, that these are the very people - the highly trained and highly skilled - who get fed up with working for a government that doesn't appear to appreciate them. That seems to be the government's aim in government positions, in the NHS and schools, for example. I imagine most paid by the state now feel like that. A Data Analyst working for the government is worth £10,000 to a private company (the cost of initial vetting) on arrival. It's not as if we don't need them either. The same is true of NHS medical staff and teaching staff. Private companies, therefore, headhunt those working for the government. Once they move governments have the costs Peter May quoted.
It's not all cut and dried. You might find this interesting. It is from an article entitled "Labour would be wise to pick its battles on outsourcing":
Our research shows that there has been both outsourcing successes and outsourcing failures. In areas like waste collection, cleaning, catering, and maintenance, and in some aspects of government back-office operations and the prison service, outsourcing has delivered significant savings and benefits to citizens.
At the same time, successive governments have overestimated potential savings – and the disaster of probation outsourcing shows that the private sector is not the cure-all that some advocates suggest. However, it is wrong of Labour’s Andrew Gwynne to claim that there is “not a shred of evidence” that outsourcing has ever worked. And there certainly isn’t enough evidence to suggest that insourcing will always work.
What I read as the accusation of the Peter May article is that Conservatives want to outsource the management of the country while they just concentrate on moving the politics. They don't seem to consider is that, in some cases, management is the very essence of their job.
