Statewide teachers' strike planned for Tuesday, December 7

Joined by principals, they will walk off the job for 24 hours on Tuesday, December 7.

Teachers Federation president Angelo Gavrielatos says he and his council voted unanimously for the stoppage in Sydney on Saturday morning.

"This will be the first 24 hour stoppage in a decade and it reflects the gravity of the situation we find ourselves in," Mr Gavrielatos said.

A statewide advertising campaign will also be stepped up with TV, radio and print advertisements focused on the failure of the government to fix teacher shortages.

"The Perrottet government is refusing to listen to the warnings of its own education department that the unsustainable workloads and uncompetitive salaries of teachers are contributing to growing shortages and turning people off teaching," Mr Gavrielatos said.

"This is about the future of the teaching profession and the quality of education children receive.

"No student should miss out because of a lack of teachers but this is what is going to increasingly happen across NSW if the government fails to act."

He said teachers and principals had, over the course of the past 18 months, exhausted all options to arrive at a negotiated settlement.

However the government's position had been fixed from day one, with a refusal to budge from a 2.5 per cent wages cap.

Mr Gavrielatos said the government had also declined to increase teachers' planning and preparation time outside the classroom, which for secondary staff, has remained unchanged since the 1950s.

The NSW industrial award that determines the salaries and conditions of teachers expires in December.

Reports suggest all 2200 of the state's public schools could be impacted by the industrial action, with as many as 60,000 teachers considering taking part.

The state government is yet to respond to Mr Gavrielatos' announcement.
