Thousands of kids in the Driffield area enjoyed an unplanned holiday on Tuesday when teachers went on strike.
Driffield School and Driffield Junior School were among those affected, along with a number of schools in villages around the town, including Hutton Cranswick.
Schools at Nafferton, Middleton, North Frodingham and Beswick were among those which remained open.
The country’s two largest teaching unions had joined forces to launch regional strikes in Yorkshire, the Midlands and the East of England over pay, pensions and workload.
A union official has warned that teachers in Yorkshire could launch more strikes after the day of industrial action hit more than 1,000 schools across the whole region.
Mike Furbank, head of children and young people, education and schools at East Riding of Yorkshire Council, said; “We are saddened by the disruption caused to children’s education. We know schools did not take the decision lightly.
“It is to be hoped that a resolution to the dispute can be found before there is further industrial action.”
Simon Jones, Driffield School head teacher, told parents in a letter on the eve of the strike that the action would potentially affect more than 80 of the 110 teachers that they employed. MP Greg Knight previously condemned the strike.
Chris Keates, general secretary of the NASUWT, said: “Strike action is a last resort, teachers have been left with no choice but to demonstrate their anger and frustration in the face of their genuine concerns being dismissed and trivialised.
“Teachers of course deeply regret any disruption to children and families. Such action would have been unnecessary had the Secretary of State been prepared to engage in genuine discussions.
“Teachers are asking nothing more of the Secretary of State than to recognise that their pay and conditions of service are directly linked to the provision of high quality education and that their concerns cannot simply be ignored.”
