The Educational Institute of Scotland (EIS) is balloting members after they rejected a “wholly inadequate” 5 per cent pay offer.
It follows a recent consultative ballot, where 94 per cent of EIS members voted to reject a 5 per cent pay offer and 91 per cent said they would be willing to move to strike action.
The union is urging members to vote yes to strike action in the postal ballot, which opened today.
