Teachers demonstrate in London as half a million education, transport and other public workers go on strike across Britain on Wednesday, calling for higher wages and better working conditions. "I think education in general, we just need more money" says Luisa Di Maria, an teacher at the rally, "more staff, more competition and teaching as well". Tony Buttifant, the National Education Union's secretary for Islington, north London, adds "this government has failed to hit its recruitment targets into teaching for a considerable number of years now... there is a crisis in our education system."
