Academy trusts, schools and councils will be “named and shamed” over “unreasonable and unfair” pay policies, the National Union of Teachers has ruled.

The NUT has just passed a motion on teacher pay which instructs the union’s executive to “target” employers which don’t pay fairly, and name and shame them “where necessary”.

It is not yet known what platforms the union will use to name and shame schools.

The motion also calls for a ballot over strike action if talks with the government over pay fail. The union wants to see an end to the pay freeze and the restoration of national pay bargaining, mandatory pay scales and the scrapping of performance-related pay.

An amendment to the motion which will see members campaign on housing affordability issues also passed.

NUT general secretary Christine Blower said: “Schools are already finding it impossible to attract staff, vacancies remain unfilled, and teachers are having to take classes for which they do not have the subject specialisation.”
