Teachers in England are to stage fresh strikes in their long-running dispute over pay.
Members of the National Education Union (NEU) will strike on 5 and 7 July, causing disruption to schools in the current term.
The NEU is re-balloting its members to see if they want to continue taking industrial action for the rest of the year.
The other education unions – the ASCL, NAHT and NASUWT – are also balloting their members for strikes over pay and funding for teachers in England.
The unions have warned of coordinated action in the autumn term if there is no settlement to the dispute.
Dr Mary Bousted and Kevin Courtney, joint general secretaries of the NEU, said it was within the grasp of the education secretary, Gillian Keegan, for the action to be halted.
“Time and again the National Education Union, alongside its sister unions, have called for the education secretary to get around the negotiation table to settle this dispute for a fully funded teacher pay increase. Time and again our calls have fallen on stony ground,” they said.
