THE NATIONAL Union of Teachers took legal action against a new aspect of the government's performance related pay scheme this week. Education ministers sneaked in rules to force teachers to inform on one another as part of the pay plan, which is due to start in September. NUT union general secretary Doug McAvoy said, "Nothing as devious and manipulative as this was ever done by the Tories." He said the union would ballot for strike action in schools where this aspect of performance related pay was imposed. That would be a step forward. But strike action and mass protests are needed in all schools to stop the whole payment by results scheme being imposed on teachers.
