While schools in Casey avoided complete closure, about 200 south-east teachers walked off the job last Thursday as they unanimously backed the Australian Education Union's resolution to conduct rolling stoppages at a meeting of more than 11,000 colleagues.

Berwick Secondary College teacher Terry McKeekin said Victorian teachers were sick of being the lowest paid in the country.

"I don't see why we are worth any less than teachers in any other states when we certainly deliver the results.

"Tests show that students in Victoria are doing as well as or better than students in other states, and yet we're doing it at a hugely reduced cost."

Government teachers want an annual 10 per cent pay rise a year, smaller classes and fewer teachers on contract employment. The Government is offering a 3.25 per cent increase.

AEU Victorian Branch President Mary Bluett said teachers were left with no choice but to take industrial action after the State Government refused to take negotiations seriously.

A spokesman for Education Minister Bronwyn Pike urged the teachers union to "come back to the table".
