The action involves stopping work for one hour at 4pm next Tuesday, November 16, and is open to Australian Education Union members and non-members.

The union planned the action to coincide with the government's reform bill likely being debated in the upper house next week, and all MLCs have been invited to speak at a gathering outside Parliament House during the stop work.

The bill will be debated in the lower house this week and is likely to pass, but the government will need to rely on independents in the upper house given Labor's opposition.

Turning TasTAFE into a government business enterprise was a recommendation from the Premier's Economic and Social Advisory Council with hopes for greater "autonomy and flexibility" in responding to industry recruitment demands.

AEU Tasmania president Simon Bailey said that seven of the eight elements of the proposed legislation were already included in current legislation, apart from having staff covered by the Fair Work Act rather than the Tasmanian State Service Act.

Mr Bailey said this could result in cuts to pay, leave and superannuation.

"If you compare the current legislation to the new legislation, it's 90 per cent copy and paste so when you hear the minister say they've started again with a blank sheet, that's just not the case," he said.

"The duties and powers of the minister are the same, the way the chief executive officer is appointed is the same.

"The government has shown nowhere in the legislation how they're going to improve education outcomes for students."

The union was also concerned that the model was similar to one implemented in South Australia where the use of private training providers increased as a result.

The AEU believed the upper house was likely to reject the bill.

The stop work action could result in some classes finishing early.

The government's proposal has received broad support from industry groups however, including the Tasmanian Chamber of Commerce and Industry and peak industry bodies in forestry, fruit growing, civil contracting, housing, carers, trades, hospitality and housing construction.

The proposed changes would come into effect from July next year, if it passes parliament.

Skills and Training Minister Sarah Courtney said the government's TasTAFE transition plan would make the institute "more contemporary".

"Our plan has the strong support of industry, and we are committed to securing opportunities for Tasmania's learners, as well as our workforce, local businesses, and our economy for years to come," she said.
