Staff who are part of the Independent Education Union (IEU) walked off the job for one hour on Monday after not enough progress was being made to address concerns relating to a new way of working.

The new system would pay teachers according to standards and not just years of service.

The proposed enterprise agreement for NSW Catholic schools would replace an existing 13-step salary model with a system based on national standards.

However, teachers are concerned this will mean a reduction in pay and a heavier workload for less income.

St Francis College IEU representative Vanessa Creece said the strike was valuable.

"It was a successful strike, with the majority of members out for the hour," Mrs Creece said.

"A motion was successfully carried, calling on the Wagga Catholic Diocese to complete negotiations and put forward an enterprise agreement by the end of the year or there may be other action taken by the union.

"College students were supervised in the playground for that period of time before school resumed at 9.30," Mrs Creece said.

Under the proposed system, teachers would be paid as either a graduate, proficient, highly accomplished or lead teacher.

Teachers in their final year of university would be classified as pre-graduate.

The IEU endorsed a motion at its annual general meeting in October that teachers receive a pay rise of 5 per cent this year.
