Councils have found another £80m to pay school staff more as they attempt to prevent mass strikes across the country, STV News understands.
Up to £30m of this is said to come from the Scottish Government – which previously said councils would have to find the cash within their existing budgets.
It’s understood local authorities were able to find around another £50m after being given more flexibility over spending.
Unions are expecting a new offer from COSLA at Thursday lunchtime.
Unison and GMB are then due to hold meetings in the afternoon to consider it.
STV News understand that the roughly £84m extra cash will be used to make a deal backdating a 7% rise to April.
Janitors, cleaners, caterers, classroom assistants and administrative staff are due to walk out in a series of strikes beginning on September 26 in a dispute over pay.
On Wednesday, Unite, Unison and GMB unions granted COSLA a grace period to improve the £1,929 increase offered last month before deciding on whether walkouts will take place next week.
COSLA now has until 5pm on Thursday to make a new offer to Unite and avoid the action, while Unison has extended the deadline until midday.
The deal covers all council workers apart from teachers who are covered under a separate deal.
