Union officials have warned there could be more action beyond a one-day strike planned for next week, in a dispute over local government pay.
The Unison union has rejected a 2.5% pay offer and members are due to strike on Wednesday 24 September. Rallies are planned for Edinburgh, Aberdeen and Inverness.
