At a protest outside Member for Swan Hill Peter Walsh's office last year, teachers announced plans for a full-day work stoppage on February 14 and plans to strictly adhere to a 38-hour work week.
Wimmera teachers could be forced to stop industrial action in their fight for better pay and working conditions when school returns next week.
Teachers, education support staff and principals from across the region began industrial action last year, including strikes, rallies and a ban on working more than 38 hours a week.
Wimmera parents also received school reports without comments or numerical assessment data in December as part of the action.
The State Government will apply for a Federal Court injunction to prevent industrial action if the union does not call off strikes and the work ban before January 29.
Goroke P-12 College principal Joy Forbes said the school's teachers were tired of the drawn-out negotiations.
"These negotiations have been going on for about two years and if the teachers had a choice they would be doing exactly what they are supposed to do," she said.
"They are very disappointed some agreement hasn't been reached between the Australian Education Union and the government."
Mrs Forbes said she was not surprised that the State Government would try to stop industrial action by seeking a court injunction.
"It surprised me that these negotiations have gone on for so long so this doesn't surprise me now," she said.
"I just think it is unfortunate that the AUE and Government can't find a resolution to these negotiations."
Horsham College principal Frank Spiel said the school was working with the union, staff members and parents to minimise the impact of industrial action on students.
"I can understand the frustration of parents and clearly it would be in the best interest of our school if an agreement was reached between the union and government," he said.
"I work closely with the union members at our school and I understand their frustration and their industrial rights.
"We will continue in 2013, as we have in 2012, to communicate with our parents and endeavour to minimise disruptions within the context of union members having the right to take industrial action to support their claims."
Australian Education Union Victorian branch president Meredith Peace said the union was asking for a 12.6 per cent pay increase over three years for teachers.
"This is another example of the Premier Ted Baillieu trying to stonewall the negotiating process," she said.
"We are extremely disappointed that the Premier continues to treat Victorian teachers with such contempt, just as we saw during the protracted nurses' dispute.
"It is time for Premier Baillieu to show some leadership and get this deal done."
Member for Lowan Hugh Delahunty said an agreement needed to be reached for Victorian students.
"We want it resolved and we want the union to come back to the discussion table an be realistic," he said.
"Students are upset and families are upset so we need to get this resolved."
