All primary, nursery and ASL schools in Glasgow are to close for two days due to strike action.
In a letter sent out on Wednesday by executive director of education Douglas Hutchison, parents and carers were told of the closures, due to industrial action, next week.
The strikes will take place on Tuesday, March 29, and Wednesday, March 30.
Secondary schools will remain open, but there will be a number of restrictions in place.
Those will include no breakfast club or mid-morning snack provision, with school meals taking the form of a packed lunch/snacks.
Pupils not in receipt of a free school meal have been advised to bring a packed lunch, as well as pupils with special dietary needs.
There will not be any after-school provision, with parents also told that escort provision for pupils entitled to transport “cannot be guaranteed”.
Parents and carers have been asked to make alternative arrangements.
Mr Hutchison issued an apology in his letter to those impacted.
“I regret that we have been left with no option but to limit our provision over the two days of the planned industrial action next week,” he wrote.
“I am sorry that you will have to make short notice, alternative arrangements for their child because of this announcement, and there will be no online learning.”
A Glasgow City Council spokeswoman said: “A letter has been sent to all our families today to inform them of the impact of the potential industrial action across the city next week.
“We have tried to reduce the impact by looking at ways in which we could keep all schools and nurseries open but unfortunately on health and safety grounds, this has not been possible.”
