Victorian teachers have announced they will hold a 24-hour strike in February over pay and conditions.
Teachers have also decided to ban overtime during the first term of the new school year after talks between the union and the Government broke down last month.
The Australian Education Union's Victorian branch president, Mary Bluett, says members will strike on February 14.
The stop-work action will affect school programs dependant on teachers' unpaid work.
"That means things like camps, excursions that go beyond the normal school day, orientation nights, sausage sizzles, fetes, productions, all of those things that involve many, many hours of additional, unpaid and unrecognised work are going to not happen," Ms Bluett said.
"The Baillieu Government has shown a complete lack of respect for public school staff in Victoria by publicly saying they want this issue resolved, but behind closed doors, not even having the decency to negotiate in good faith and respond to what is a very reasonable offer." She said the union will also introduce a 38-hour-week campaign from the start of the school year and will develop a schedule of half-day rolling regional stoppages commencing in the second term.
