School staff in Stirling and Clackmannanshire are to strike next month.
Trade union UNISON has served notice for industrial action on 6th, 7th and 8th September.
It's expected to cause disruption in schools, early years centres and nurseries across the area.
Johanna Baxter, UNISON Scotland head of local government, said: “We are in urgent negotiations with the employer to try and find a solution, but so far we have only had an offer of talks - we have not had a pay offer. Until we can explain to UNISON members how a pay offer might impact on them, council workers have been left with no choice but to strike.
“UNISON has been demanding pay talks for months and COSLA and the Scottish Government are still dragging their heels. Inflation is predicted to rise to more than 13%, and our members are struggling as fuel, food and household bills go through the roof.
“Until we have a decent pay offer that we can put to UNISON members our strike action will continue and thousands of school and early years workers will be talking action across nine councils in Scotland.”
