Teachers back Unison's industrial action plan over pensions

One of the UK's biggest trade unions says pension reform plans could trigger the biggest wave of industrial action since the General Strike in the 1920s.

Unison leader Dave Prentis said unions were prepared for "sustained and indefinite" strikes over proposed changes to public sector pensions.

Dr Mary Bousted is the general secretary of the Association of Teachers and Lecturers. She told the BBC that she understood the anger of Unison and explained why her members would go out on strike.
