Tasmanian teachers, health workers, firefighters and other public sector employees in the state's north-west have walked off the job, as the fight over pay and conditions intensifies.

Further action is planned for Launceston and the rest of the north tomorrow, and then in the state's south on Thursday.

The tension has been brewing for weeks, with unions rebuking the state government's temporary offer of a 3 per cent pay rise for the first year, while they negotiate a long-term deal.

The government offer also includes changes to leave, including parental, medical, reproductive, gender affirmation and pregnancy loss entitlements.

But it has been rejected, with workers claiming they had been treated with "contempt", pushing hundreds to rally at Burnie and Devonport.
