Tasmanian public schools to remain open on the afternoon of March 10 as union calls off strike action

The government announced on Tuesday classes in public schools would finish up at 1pm on Friday as teachers were due to walk off the job in protest over workload from 1.30pm.

However, the union on Wednesday issued a statement to say the action had been called off after a last-minute commitment from the government to put forward an improved offer to educators.

Australian Education Union Tasmania President David Genford said the state government could have avoided an early school closure by providing an offer with in-class support last week - or at any point during 18 months of negotiations.

"The only time the Rockliff Government has shifted is when stop-work action is on the table," he said.

"It should not have taken a planned walk-off and strong union action for the government to deliver students what they desperately need.

"It also shouldn't have taken 18 months for the Rockliff Government to act on the need for more in-class support in schools and colleges as teachers increasingly walk away from the profession citing burnout."

Education Minister Roger Jaensch said the government would present a final wage offer this week.

"The AEU has committed to providing this offer to its members," he said.

""Importantly, our hardworking education staff will shortly have the opportunity to vote on an offer that will give them a fair and affordable pay rise, as well as additional in-class support roles and improved support for early career teachers."
