Members of NASUWT Teacher's Union will begin action short of strike action from tomorrow.
It comes after members were balloted earlier this month after disputes over pay, workload and working practices.
94% of respondents voted for action short of strike action.
From tomorrow, teachers will no longer take part in activities that don't directly relate to teaching and learning, including responding to emails outside of pupil session times, providing cover for absent colleagues, or submitting lesson plans.
