School staff in Stirling and Clackmannanshire are to walk out later this month.
Trade union UNISON says workers - including cleaners and caterers - will strike on Wednesday 15th November.
They've rejected a pay offer from council body COSLA.
UNISON Scotland’s head of local government Johanna Baxter said: “The strength of feeling among UNISON’s 91,000 local government members, who voted overwhelmingly to reject Cosla’s latest pay offer, is clear. They are determined to continue to fight to get an improved pay offer.
“While no deal has yet been reached, we continue to have constructive dialogue with Cosla and we remain committed to resolving this dispute as soon as possible.
“Cosla and the Scottish government need to give local government workers a decent wage rise, fund any increase properly and commit to implementing a minimum underpinning rate of pay of £15 per hour for all local government workers.”
