COFFS Coast parents are being urged to check arrangements with their schools following the decision of teachers to hold stop-work meetings for two hours on Friday.
At the stop-work from 9am, public school teachers will be updated on the Local Schools Local Decisions policy.
Teachers' Federation president Maurie Mulheron said the strike was necessary following the Minister's failure to provide guarantees on staffing, class sizes, curriculum, salaries and security of employment.
"The Government is carrying out its reforms in haste and with secrecy," Mr Mulheron said.
"This is the biggest restructure of NSW education in history.
"It will have a very serious impact on students and teachers and the resourcing of our public schools.
"If allowed to proceed it will certainly mean the loss of permanent positions from schools.
"This will affect every principal, classroom teacher, executive teacher and specialist support teacher."
