More school strikes are being planned across Scotland as staff continue a dispute over pay, a trade union has announced.
Unison has written to COSLA and the Scottish Government warning that any future walk-outs are likely to be even bigger as it reported a surge in members.
Non-teaching staff took part in three days of industrial action this week which saw hundreds of schools across 24 local authorities close.
Unison said 21,000 members walked out across 1,868 schools.
The action involves non-teaching staff including support assistants, catering staff, cleaners and janitors.
The Unite and GMB unions suspended strikes last week to consult their members on the offer but Unison said it would continue with its plans, labelling COSLA’s deal “too little too late”.
