The ballots have been counted and despite 90% of the votes being in favour of strike action, only 42% of members returned their ballot therefore the 50% threshold of membership voting was not reached and strike action will not take place.
This is for NASUWT members, the second biggest teaching union. The largest teaching union, the NEU, will be announcing its results early next week (possibly Sunday). The NAHT headteachers' union will also be announcing strike ballot results shortly.
If the NEU strike and the NASUWT don't, schools still may close. If headteachers strike, who knows as it has never happened before.
