Four unions representing hundreds of thousands of teachers and leaders have urged members to hold joint staff meetings in all schools to boost their ballots for strike action.
Leadership unions the NAHT and ASCL, along with the NASUWT teaching union and National Education Union, have written to their members today to encourage the meetings.
They warned they were “now in a battle for the very future of education”, urging members to “stand with your colleagues and join us as we strive to bring about real change.”
All four unions are balloting members for strike action over pay, funding and other issues facing their members, and have pledged to coordinate walkouts in the autumn term if they are successful.
