Schools will be hit by escalated industrial action by teachers from today in a row over jobs, pay, pensions and workload amid "deep concerns" among staff over their profession.
Members of NASUWT will only produce one written report a year to parents, will not submit lesson plans to senior managers and will refuse to invigilate mock exams.
Teachers will be able to supervise activities outside school hours, such as sports clubs and drama, if they are happy to do so, but will refuse if it is imposed on them by a headteacher.
Union members will also only send and respond to work-related emails during school hours.
The National Union of Teachers (NUT) will undertake similar action from October 3.
