A 16-day wave of rolling teachers strikes has begun in Scotland, with every local authority affected over the period.
Members of the Educational Institute of Scotland (EIS) will strike in two local authorities per day from 16 January until 6 February.
Union leaders have warned there is no end in sight to the current pay dispute.
Teachers want a 10% uplift, which ministers and councils have said is unaffordable.
The current 5% offer includes rises of up to 6.85% for the lowest-paid staff.
