Teachers in the NUT and NASUWT unions are preparing to take industrial action from Wednesday of next week. They can refuse to carry out duties such as some appraisals and some classroom observations in certain conditions.
The unions announced the action following a successful ballot in the NUT for action over pay and conditions. The union has an existing dispute over pensions.
Many teachers are disappointed that the NUT leadership failed to call strikes despite a strong vote backing them. Yet workers are preparing to make the action as successful as possible, in many areas holding joint meetings to plan their campaigns.
Teachers in the UCAC union in Wales are balloting for strikes over pay.
