While the National Education Union (NEU), the Association of School and College Leaders (ASCL), the National Association of Head Teachers (NAHT), and NASUWT have accepted a 6.5% pay rise from the government, NASUWT has continued its campaign for improved pay and working conditions.
This action involves working to rule, which may affect staff at around 10,000 schools.
Teachers in Northern Ireland and NAHT members in Wales have also taken action short of a strike. The pay dispute in Scotland has been resolved.
The primary issue for the teachers has been pay, with unions initially calling for an above-inflation pay rise. While the government offered an additional one-off payment of £1,000 and increased the offer for most teachers in 2023-24 to 4.3%, the unions rejected the deal.
The independent pay review body recommended a 6.5% pay rise, which led to the unions accepting the government's offer.
