Dubbo NSW Teachers Federation Organiser Mercurius Goldstein says there's an easy fix to the ongoing problem of pay disparity between teachers.
Since the Department of Education's implementation of its new pay scale in 2016, teachers employed from 2016 onwards are being paid more than their more seasoned colleagues.
"The transition to standards-based pay, while a positive for the profession overall, has created a significant problem for teachers who commenced teaching before 2016," Mr Goldstein said.
"We have a situation where less experienced teachers are being paid higher rates."
Mr Goldstein roughly estimated as much as a $9,000 difference between the two categories of teachers every year.
"Worst case scenario, throughout a lifetime, there would be a roughly estimated $50,000 difference between teachers who commenced before 2016 and who commenced after," he said.
A spokesperson for the NSW Education Minister disagreed with Mr Goldstein's claims.
"While it is possible for a new teacher remunerated under the new structure to reach a higher salary during a shorter period of time, no teacher has suffered a salary decrease," the spokesperson said.
According to Mr Goldstein, the issue would be rather easy for the State Government to resolve.
"For the State Government to fix the overall problem, it would cost them around $22 million," he said.
"Now, compare that to the billions of dollars the State Government spend on other projects, $22 million is a rather insignificant amount."
According to Mr Goldstein, the Federation has pursued this matter with the Department and State Government without a successful outcome at this stage.
Mr Goldstein says the Federation will continue to pursue the matter with the NSW State Government.
"We will encourage and support members to pursue at a local level, demand a successful resolution to the inequities and prioritise this issue in the forthcoming award negotiations," he said.
The Minister's spokesperson said due to the concern the implementation has caused teachers who are subject to the transition provisions; the department will ensure this issue is considered in the next award negotiations which are due to start in 2019.
