A sign was erected at the school's entrance saying the community stands with teachers. 

It is understood parents got together and created the sign. Teachers at the school have branded it a "pretty huge response". 

About 1000 people attended the stop work meeting in Launceston, with assistant secretary of the Health and Community Services Union Robbie Moore saying it was disappointing it had come to this. 

"The government has failed to meet with the workforce and treat them with any respect so workers are taking action," he said. 

The dispute has been going since late last year and involves health workers, emergency services workers and teachers. 

United Firefighters Union representative Jeremy Patterson said firefighters found the government's latest offer disrespectful and a "slap in the face".

"We received the offer and there were some very angry people in the membership of the TFS," he said.

Mr Patterson said firefighters want Treasurer Peter Gutwein and Premier Will Hodgman to come to the Launceston station and speak to them.

Launceston teacher Alison Jales said teachers, who are just eight weeks into the school year, are already talking about not renewing their contracts because of the stress. 

Treasurer Peter Gutwein called on the unions to stop playing politics. He said the teachers are some of the best and brightest in the state, but were being denied the opportunity to look at the offer in full. ​

Also on Wednesday, about 100 Metro bus services were interrupted while staff stopped work for a 5 per cent pay rise.
