Two teachers' unions are threatening to ballot members on taking action over workload.
The National Association of Schoolmasters Union of Women Teachers this week launched a campaign, Let Teachers Teach, which aims to "banish mindless bureaucracy". Nigel de Gruchy, general secretary, said the Government has failed to solve the paperwork problem.
Next month the union's executive will decide whether to ballot members on action.
The Association of Teachers and Lecturers' conference will also consider balloting on industrial action. Peter Smith, general secretary, said: "If the Government is serious about relieving the demands on teachers, it should be reducing class sizes and ending the climate of fear created by 'name and shame' politics which send teachers on an anxious paper chase."
