Dissatisfaction among secondary college teachers about the Premier's education changes could lead to a state-wide teacher strike.

The Education Union is holding a third stop work meeting in Hobart this afternoon.

The union says teachers at last week's Ulverstone and Launceston meetings were overwhelmingly against the controversial post-year ten 'Tasmania Tomorrow' changes and it expects the same result today.

Spokesman Greg Brown has warned Premier David Bartlett to respond or face the consequences.

"It is a very, very real possibility that there will be a state-wide strike before the end of the year," he said.

The Education Union's TAFE Division President, Ross Dale, says TAFE teachers are not only supporting secondary college teachers, they have their own problems with the new system.

"The TAFE division executive met on Friday and we have mapped out certain strategies to follow, to take in continuing the industrial action," he said.

Primary and Secondary teachers are considering whether to join the action.

Tech fury</h3>;

Teachers at the Australian Technical College in northern Tasmania are furious the college is being pushed to the State Government's unpopular post year-10 education system.

The campuses at Burnie and Launceston were created by the federal Coalition Government, but the Labor Government did not want them.

In the last year, the College has been passed from the Federal Government to Catholic Education and now to the State Government.

The State Government will turn the Burnie and Launceston College campuses into Polytechnic schools.

A senior teacher at the Technical College, Mark Kenzie, says now the future of 270 students and 35 staff is up in the air.

Students at the College complete Year 11 and 12 at the same as they start their apprenticeships.

Mr Kenzie says they work around industry demands, which is not how the Polytechnic system operates.

"A lot of these students won't have jobs next year because of the inflexibility of the Polytechnics," he said.

Technical College staff will meet with concerned parents of students later this week.

Mr Kenzie says their contracts run out in December and the 35 staff don't know if they will have jobs next year under the new Polytechnic system.

"We've really pushed the issue with the board and with different politicians to give us a definite answer," he said.

"We have known since at least the 21st of August when the Catholics did say they didn't want to take it over that we weren't going to be around next year, or the possibility of not being around next year, so we've all been wanting to look for jobs but were unsure whether we should or not."
