The Tasmanian Government is under mounting pressure to resolve a dispute which will shut down commuter bus services on Friday morning.
More than 300 bus drivers will walk off the job across Tasmania between 6:00am and 9:00am on Friday after pay talks broke down.
Metro Tasmania is offering a pay rise of 2 per cent a year for three years but drivers want 3 per cent.
The Education Department says schools will be open as usual but there is no decision yet on whether private buses will be hired to fill the shortfall.
St Virgil's College in Hobart is hiring eight buses to ensure several hundred senior students make it to school but parents will have to drop off junior pupils.
The Catholic Education Office is advising parents to make alternative arrangements if they usually rely on school buses.
The Transport Minister, Greens leader Nick McKim, is on annual leave and the Opposition is calling on him to return early to deal with the situation.
"What a struggling economy does not need is a crisis in public transport," Opposition spokesman Matthew Groom said.
"The Government needs to take charge of this situation and fix it."
The Premier Lara Giddings says she does not believe that is necessary.
"It's not appropriate for Ministers to step into an industrial process," Ms Giddings said.
It is expected up to 13,000 people will be inconvenienced by the strike.
