More than 105 Independent Education Union member teachers and staff from eight Northern Catholic primary and high schools marched in Launceston this month after a 17-month negotiating stalemate.

Students were left with relief staff to teach in the striking teachers' absence.

Those same teachers, along with 292 members statewide, will not turn up at work on August 7, unless the Tasmanian Catholic Education Office acts with a fair and reasonable offer.

Independent Education Union assistant secretary Angela Briant said it was not a step taken lightly by the members, who were exasperated by the lack of respect shown by the Catholic education system.

Tasmanian Catholic Education Office director Trish Hindmarsh said a meeting between its key stakeholders would be held tomorrow to discuss a response.

Dr Hindmarsh said meetings had been delayed as some key stakeholders had been interstate and overseas.

"As schools have been on holidays over the last fortnight it hasn't been possible for the employers to engage in appropriate processes of decision- making regarding the current industrial circumstances," Dr Hindmarsh said.

"Since schools have now resumed for term 3, the employers have arranged for their key stakeholders to meet to discuss the matters and to decide how best to move forward."

Ms Briant said the delays were unacceptable.

"Almost a month after taking strike action, the TCEO has barely lifted a finger to try and resolve outstanding matters of concern," she said.

"They can stop this strike from happening but they must be prepared to move on these key issues."
