Two-thirds of public school teachers feel burnt out, a NSW government-commissioned survey has found, which the union says shows an education system in "crisis".
The 2022 People Matter Employee Survey, which received responses between August and September, revealed less than one-third of teachers say they can keep their work stress at an acceptable level.
Less than 20 per cent believe they have time to do their job well and are fairly paid.
NSW Teachers Federation President Angelo Gavrielatos says the new figures confirm the extent of the classroom crisis, with the results far worse than previous years.
"This is the government's own research confirming we have a crisis in the teaching workforce due to unsustainable workloads and uncompetitive salaries," Mr Gavrielatos said on Wednesday.
A whopping 67 per cent of NSW teachers surveyed said they felt burnt out, with 63 per cent saying they would quit the profession within the next 10 years.
Mr Gavrielatos said the high rate of teacher burnout and overwork was reflected in the growing staff shortages.
"The Perrottet government is failing teachers and failing students," he said.
New government figures show there are almost 2500 permanent teaching positions in NSW public schools, an increase of almost 150 per cent since June last year.
"You can't fix the teacher shortage problem without fixing the wages and workload problem," Mr Gavrielatos said.
Almost one-in-10 say they will be gone within a year, with 21 per cent saying they will quit in the coming two years.
Only 19 per cent say they are fairly paid for the work they do.
"The number of early career teachers leaving public schools is also at a 13-year high," Mr Gavrielatos said.
"From Bondi to Broken Hill and Cronulla to Coonamble... every part of the state is being impacted (from shortages)," he told AAP.
The survey comes on the back of a parliamentary report into the state's teacher shortage released on Tuesday.
It made 20 recommendations to lift the status of teaching and return it to a "highly valued and honoured profession in the eyes of the public and school leavers in particular".
"This means adopting modern professional standards and expectations for teachers' performance, working conditions, scrutiny, enhanced professional development, promotion, job certainty and financial rewards," it said.
The committee heard of teachers reporting heavy workloads, increased administrative burdens and a decline in both teacher and student morale.
"The pipeline of new teachers entering the profession is inadequate, and ... attrition rates are high resulting in an insufficient supply of teachers," the report said.
Labor leader Chris Minns said on Wednesday he would turn 10,000 temporary positions in full-time jobs and slash untenable workloads if elected to government in March.
Thousands of NSW teachers have gone on strike several times this year chiefly asking for a 7.5 per cent pay rise.
AAP has contacted the Department of Education for a response.
