More than 160 preschools and public schools across South Australia were closed today as frustrated, angry teachers descended on state parliament demanding better pay and conditions.
Thousands of teachers arrived at state parliament on Friday in the first strike action since 2019.
Here's what we know about the industrial action.
What happened in the strike?
Thousands of teachers walked to the steps of parliament with banners and demands, hoping the show of force will make the government listen.
"We're so overworked and so overstretched and we're at breaking point," one teacher said.
"There's just not enough support for teachers or the kids - especially the ones with learning difficulties," another teacher said.
"We're losing a day's pay - we don't want to be here, but we're fighting for the kids. We're fighting for the kids in our class," another added.
After the huge turnout on Friday, the union isn't ruling out further industrial action until it gets the offer it wants.
How many schools were impacted?
There were 167 public schools and preschools closed.
An additional 152 public schools and preschools were open in various capacities, including some running reduced programs for students.
There were 608 schools operating as usual.
Some parents only learned of the strike on Friday morning when they tried to drop their kids off at school.
"(I) wondered why the back gate was locked and came round and found out there's a strike on, so off home we go," a parent said.
What are teachers striking for?
The union said failed negotiations with the government have been underway for nine months.
The union wants an 8.6 per cent pay rise in the new enterprise agreement with the government, followed by a 5.5 per cent increase in the two years after.
It also wants a support officer in every classroom.
There are also calls for teachers to have more time to complete admin work.
After a number of meetings since the union agreed on industrial action about 5pm on Tuesday, union branch president Andrew Gohl said there had been "some understanding" from the government about the pressures on the workforce.
"At the moment there's still an issue around workloads and there's still an issue around pay and a number of other matters," Gohl said.
What has the government said?
The South Australian government offered a 3 per cent pay increase per year over three years, but the union said that doesn't "come close to supporting a workforce at breaking point".
Education Minister Blair Boyer earlier made it clear the government didn't want teachers to strike.
Boyer said negotiations are continuing and hoped to come to an agreement with the union.
"We are negotiating in good faith," he said.
"It doesn't mean we're just going to agree with the terms of the union. That wouldn't be the wise thing to do, we need to come to an agreement.
"I think we are moving in a positive direction."
