NASUWT

NASUWT – The Teachers' Union is a trade union representing teachers in the United Kingdom across all phases of education, affiliated with the Trades Union Congress, the Scottish Trades Union Congress, the Irish Congress of Trade Unions and Education International. It is one of the largest teaching unions in the UK and is distinctive in representing only qualified teachers, rather than a wider group of education staff.

The union describes itself as "the undiluted voice of the teaching profession," emphasising that its work is centred exclusively on teachers’ interests.

The union engages in negotiations with employers, campaigns on pay and workload, provides legal and professional support to members, and, when necessary, takes industrial action.

Membership is open to teachers at every stage of their careers, including those in supply roles, leadership positions, and in both the maintained and independent sectors.
