Busloads of teachers will converge on Melbourne today as part of an ongoing industrial dispute over pay and conditions.

The Australian Education Union said the strike was the beginning of a ramped up industrial campaign.

Teachers will today vote on another 24-hour strike and rolling stoppages at sites around the state, including Ballarat.

The union said teachers were "angry" they had not had a pay rise since September 2006, despite their state secondary school colleagues getting a big wage increase in May.

A TAFE teacher at the beginning of their career would earn $9000 less than an equivalent government school teacher.

"There is nowhere else for TAFE teachers to turn now. We have to do this," AEU TAFE vice president Gillian Robertson said.

"This is the start of a very loud industrial campaign. We've got a hell of a lot of very angry teachers."

Union officials may face fines over the strike, which was not protected by industrial law.

University of Ballarat Vice Chancellor Professor David Battersby said he expected some disruption to classes as a result of the strike.

"I can't tell you how many teachers will be involved but clearly there will be an impact," Prof Battersby said.

He said while the university would have preferred to have avoided disrupting students' schedules, it understood the teachers' position.

"The fact that our TAFE teaching staff have not had a salary increase since September 2006 is not a good position for them to be in," Prof Battersby said.

"We think now is the time for the State Government to respond."

The university this week announced it had agreed to a 10.9 per cent pay increase for its tertiary academic and general staff.

"Two thirds of the institution has now had a collective agreement which is now going to the vote for approval.

"It would be really conducive for us as a managing institution if the settling of the TAFE teachers' award is done expeditiously."

A spokeswoman for State Minister for Skills and Workforce Participation, Jacinta Allan, said the government believed TAFE teachers deserved a pay rise, and the best way for them to secure it was to return to the negotiating

table.
