Teachers across the county are preparing to strike on Wednesday over pay, pensions and working conditions.
National Union of Teachers Suffolk secretary Graham White said although the walk-out was regrettable, it was necessary to protect the future of the profession.
He said: “We know teachers’ working conditions are getting worse.
“They are working hours in excess of 60 in a week so staff end up working weekends too.
“We know teachers pay is also going to be held back but the biggest single issue is pensions. “The Government has received £46 billion more than it has paid out but claims there is a shortfall in the pension scheme.
“Most important of all is we are trying to get Mr Gove to listen to teacher trade unions and get round the negotiation table and have constructive talks.
“It is regrettable we have to go on strike as it means teachers will miss out on a day of pay and regrettable because children may miss a day of learning. “But if we don’t make a stand now we will see the teaching profession made considerably worse in the future.”
Mr White said he didn’t know how many schools would have to close but expected the disruption to be ‘substantial’.
