The first national ballot on industrial action in school leaders’ union ASCL’s 150-year history will run from June 19 to July 31, it has been confirmed.
It comes as a long-running pay dispute with the government, which has seen three other education unions launch similar ballots, continues.
The vote, which was announced in April, will ask its members in England whether they are prepared to take part in strike action.
If the ballot passes the legal threshold, strikes are expected to take place in autumn and be coordinated with other unions.
