The NASUWT union has informed the council of planned industrial action at Rosshall Academy on Tuesday 8 October and Wednesday 9 October.
Glasgow has issued the following press statement:
Council spokeswoman said: "It's deeply regrettable that the NASUWT union has not called off the planned strike action at Rosshall Academy next week despite the council's best efforts to try and reach a resolution.
"In fact, the union has declined to either sit around the negotiating table or respond to numerous communications - including an offer to not process deductions for those teachers who have not attended agreed activities which take place out with the pupil day.
"This is what we understand to be the main point of the dispute and are therefore puzzled as to why the union is determined to continue with their planned action that will obviously result in a two day disruption to the pupils' education at the school.
"We would urge senior officers of NASUWT to accept our offer to talk and reach a satisfactory conclusion for their members that will not impact our families as they have advised us of more action in other schools across the city."
A parents' letter has been sent to Rosshall Academy families and a letter issued to staff.
