Teachers have walked out of a Sydney public school as the NSW premier and education minister arrived in defiance of a union ban.
Dominic Perrottet and Sarah Mitchell attended the opening of a new school at Meadowbank Education Precinct in northwest Sydney on Wednesday.
Their arrival on the first day of term two prompted teachers to leave the campus and stand outside the school, holding signs saying, 'More than thanks'.
It comes after the NSW Teachers Federation executive voted on Tuesday to strike for 24 hours next Wednesday.
The union also imposed a ban on NSW government MPs visiting schools, authorising teachers to walk out if they arrived on campus.
The Teachers Federation tweeted pictures of teachers protesting outside the school.
"This morning Premier Perrottet and Minister Mitchell walked into Meadowbank Education Precinct.
"Our members walked out. Send your message to the Premier on May 4," it tweeted.
Earlier on Wednesday Ms Mitchell criticised the planned strike, saying it would disrupt families and students.
"I'm pretty disappointed, I'm on the side of the parents here," Ms Mitchell told Sydney radio 2GB on Wednesday.
"It's frustrating, I think our kids have had a lot of disruption over the last couple of years," she said.
The union did not need to strike to negotiate a new award, she said.
"They just need to be in the (Industrial Relations Commission) with us and they will get an outcome."
The case is due to come before the Industrial Relations Commission next month.
Most schools would offer minimal supervision for students whose parents could not make other arrangements on Wednesday, Ms Mitchell said.
The teachers' union suspended its industrial action in December to negotiate with the government, before accusing the government of squandering the opportunity.
"What we're seeking is a competitive salary for teachers, a salary that is commensurate with other professions," Teachers Federation President Angelo Gavrielatos told the Seven Network on Wednesday.
"We're at a point in Australia where inflation is now at 3.8 per cent and predicted to increase above four per cent but the government continues to pursue increases of 2.04 per cent, effectively inflicting a pay cut for teachers."
The union wants a pay rise of between five and 7.5 per cent, as well as two extra hours of planning time.
AAP has contacted the office of the NSW Premier and the NSW Teachers Federation for comment.
