One in five secondary schools and one in ten primaries were braced for disruption this week as members of the NASUWT teaching union began limiting their working time.
Polling by Teacher Tapp shows 14 per cent of secondary teachers and 5 per cent of primary teachers planned to participate in the action short of strike, which began on Monday.
Members are taking the action as part of an industrial dispute over workload. According to a landmark government survey leaked to Schools Week earlier this year, teachers work on average 48.7 hours a week, while leaders work 56.8.
NASUWT’s action includes restrictions on meetings and refusing to be directed to undertake extracurricular activities and midday supervision.
