Scottish Secondary Teachers’ Association (SSTA) members were balloted for strike action after rejecting a 5 per cent pay offer, and 90 per cent voted for strike action on a turnout of 62 per cent.
The SSTA said that members in some local authority areas will strike on Wednesday December 7 while others will walk out on Thursday December 8.
Catherine Nicol, SSTA president, said: “The executive committee felt it had no option but to move to strike action due to the failure of the employers (Cosla) and the Scottish Government to make an improved pay offer.
“The last pay offer was made on the August 19 and was quickly rejected by the teacher unions. Despite a series of engagements, not even one more penny has been put on the table.
