Pupils in Scotland are facing more disruption as teachers prepare to strike again in the coming weeks.
Elsewhere in the UK, teachers are also considering industrial action over pay.
A national teachers' strike will take place on 10 and 11 January. One day will target primaries, the other secondaries. In the following weeks, every school will face a further strike.
Nearly every primary and secondary school, as well as many nurseries, were closed by a national strike on 24 November. It was carried out by members of the Educational Institute of Scotland (EIS) and the Association of Head Teachers and Deputies Scotland (AHDS).
A strike by other unions on 7 and 8 December led to some schools being partially closed.
