Strikes that will close schools across Scotland are set to go ahead after a union rejected a new council pay deal.
The Scottish government freed up £80m so local authority body Cosla could improve the offer, which would have included a rise of about £2,000 a year for the lowest paid.
It has been rejected by Unison whose members will walk out on 26, 27 and 28 September in 24 council areas.
The union described the latest offer as "too little, too late".
The GMB and Unite unions are still considering the deal.
The dispute is over a pay offer for all council workers other than teachers - who are covered by a different deal.
A number of councils - including Glasgow - have already said schools will close if the action goes ahead.
Unison Scotland's head of local government, Johanna Baxter, said: "We cannot agree to a pay offer that will result in further cuts to our members' jobs and the services they provide.
"These are not well-paid staff, they are on less than the Scottish average wage and it is simply not acceptable."
A deadline was originally set for 17:00 on Wednesday for Cosla to make an improved pay offer - but it asked for an extension to seek funds from Deputy First Minister Shona Robison.
