sorry, but going back a bit here and not related to the current discussion as it has turned today, but...
Mr Elms, who runs a school of 400 pupils, was paid a basic salary of £82,714 last year apparently [according to bbc]. The rest was back pay for over time [covering 2 years worth]and one project related to his field. there is a cap on headteachers pay of around 109k i understand.
as for Francis Maude being so and mighty about 'public duty' and working for the love of it? he was paid more than £6,000-a-day for his work as an adviser to Barclays Bank on top of his earnings as an MP.
If MP's are allowed to take up second jobs, so why not other public workers, such as Elms? At least Elms is doing something actually worth while. He was chosen to do that job as he had the expertise and he succeeded. just as someone in the private sector might get a bonus for earning their company lots of money, he got paid for helping young disadvantaged children get on, who otherwise, would not have/will not. I know which I would reward more generously.
There wouldn't be lots of private sector workers who could fill Elms role as his is specialised as is most of the work done by the public sector. you can't be a salesman for double glazing and then decide overnight to be a head for example. just as a head couldn't suddenly run a hospital. There are more graduates in the public sector than private, a more specialised workforce, it is just not that simple imo.
