A ballot has begun that could see council workers take strike action unless local government bosses increase pay by 2%.
The decision of the ballot could see up to 10,000 council workers take strike action later this summer.
Trade union GMB will send a statutory notice to Convention of Scottish Local Authorities (COSLA) chiefs on 30 May to inform them that a ballot of all members in schools, early years and waste and cleansing services in councils has started.
