Is teacher's £200k pay a scandal?

"In fact Elms, who runs a school of 400 pupils, was paid a basic salary of £82,714 last year. But he also received more than £100,000 - £51,957 of which was backdated pay for 2008/09 - for work on a programme introduced by the Labour Government to tackle underachievement in disadvantaged areas. He was also paid £10,000 in overtime for 2009/10, and a further £9,317 for overtime in 2008/09." -- AOL website.

Hang on a minute... Why the hell is a headteacher who is earning a "basic" salary of £82,714 being paid overtime? I didn't think those positions paid overtime. How did he manage to be paid this? HOW?

Rant over.
