Unions have agreed to exclude Kingspark Primary from the strike to protect pupils at the special needs school from unnecessary disruption to their education.

Claypotts Castle Primary is excluded too because it has been built under private public partnership and under the terms of the deal, auxiliary staff, such as janitors, are employed through private contractors rather than the local authority.

The strike was called after the unions, Unison, GMB and Unite (T&G), turned down a 2.5% pay offer for the next three years. They want a 5% increase or £1000 — whichever is greater — from April 1 this year.

Youngsters in Perth and Kinross looking forward to the start of school will also enjoy only one day before the industrial action forces them back home.

The local council has confirmed all authority schools and nurseries will be closed throughout Wednesday.

Because of the lack of staff, after-school clubs and any school lets have also been cancelled for the day.

It has pledged to let the public know immediately through its website.

The action is likely to disrupt services and close schools throughout Fife, the Kingdom’s local authority has warned.

It is not yet known how many of Fife Council’s 9000 union members will stay away from work in support of their pay claim, but some school closures are highly likely.

Normal council services will resume from next Thursday morning.

More information about service disruptions across Fife and registering for closure alerts will be available on www.fifedirect.org.uk

Angus Council said today it did not yet know the extent of any possible strike action impact on the district’s schools and nurseries.

“We are still in the process of trying to establish how much disruption there’s likely to be,” said a spokesperson.

The authority has said details of service disruptions will be posted on the Council website.
