The Greenshaw Learning Trust (GLT) has primary and secondary academies based in London, the South East and South West regions. The NASUWT, along with the other workforce unions, has negotiated a trade union recognition agreement with GLT for consultation and collective bargaining purposes.

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

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