School and nursery staff in nine Scottish council areas are to go on strike for three days next month in a row over pay, it has been confirmed.
Unison and the GMB said their members will strike on 6, 7 and 8 September after talks with council body Cosla failed to reach an agreement.
School and early years staff will join waste and recycling workers who have already started strike action.
Unison said a total of 13,000 members would be involved.
It will see schools, early years centres and nurseries disrupted in Aberdeenshire, Clackmannanshire, East Renfrewshire, Glasgow City, Inverclyde, Orkney, North Lanarkshire, South Lanarkshire and Stirling.
The unions represent workers including school catering staff, cleaners, caretakers, teaching assistants and early years practitioners.
