Rubbish collections were also set to be hit - it's expected there will be no collections throughout Roxburghshire. And the recycling depot in Hawick is closed. The impact on other areas in the Borders is not known as yet.
Members of three trade
unions UNISON, GMB and Unison in the country's 32 local authorities are taking industrial action after rejecting a pay offer of 2.5 per cent for each of the next three years.
Teaching staff are not involved in the 24-hour stoppage but some support staff will be taking action.
The classroom closures come just one day after pupils returned after their summer holidays.
A spokeswoman for Scottish Borders Council commented: "Where schools or nurseries cannot maintain adequate staff ratios to ensure pupil safety, they will be closed.
"For the schools that are open, there will be no school lunches on Wednesday and it is therefore important that parents send their child to school with a packed lunch. A packed lunch will be provided to all pupils who are entitled to free school meals."
Threat to school transport - advice to parentsSchool transport may be hit and pupils are advised to follow the standard guidance: if no bus arrives after 20 minutes, pupils should go (or be taken) home. Parents can transport their child to school themselves, but if so they should make arrangements to collect their child at the end of the day.

SECONDARY - Earlston, Galashiels, Hawick High and Kelso
PRIMARY - Stirches, Burnfoot, Drumlanrig, Wilton and Trinity in Hawick ( Stirches nursery remains open); Glendinning Terrace in Galashiels; Howdenburn in Jedburgh; Knowepark in Selkirk; Cockburnspath, Ayton, Earlston, Newcastleton, Reston, Newtown St Boswells,
