Thousands of council workers across the Forth Valley are considering strike action in a dispute over pay.
Trade unions Unite and GMB have rejected a 2% offer from the COSLA.
The unions have now confirmed they'll ballot members across the country.
Nearly 10,000 members of staff across Scotland could strike.
Unite general secretary Sharon Graham said: “The last offer on the table from the employer was a pathetic 2%.
“Our members are not putting up with this and they will have their union’s full support in the fight for better jobs, pay and conditions in local government.”
GMB Scotland senior organiser Keir Greenaway says:
“Tens of thousands of the lowest paid staff in local government will go from the frontline of public service delivery to below the breadline unless their pay confronts soaring inflation and eye-watering energy bills,”
In a statement, a COSLA spokesperson said: “We remain in active discussions with our trade union partners.”
