The Warriner Multi Academy Trust (WMAT) has primary and secondary academies based in South East and East Midlands regions. The NASUWT, along with the other workforce unions, has negotiated a trade union recognition agreement with WMAT for consultation and collective bargaining purposes.

This provides the necessary structures for the NASUWT to meet with WMAT at a national level and on a regular basis in the WMAT Joint Consultative and Negotiation Committee (JCNC). The JCNC is where the trade unions meet with WMAT to negotiate on pay, conditions of service issues, and policies and procedures for teachers and other WMAT staff.

WMAT currently employs teachers according to the School Teachers' Pay and Conditions Document and Burgundy Book in all their academies.
