Teachers and local government employees are expected to take part in a nationwide strike over pay conditions on July 10.

Havering Council has said it can not predict how severely the strike will affect the borough as employees are not required to announce their intentions ahead of the walk out.

Councillor Melvin Wallace, cabinet member for culture and community engagement, said: “We will do our best to maintain all council services throughout the strike action.

“The council’s call centre and the Public Advice and Service Centre are likely to have fewer staff than normal working on the day, which could lead to longer waiting times – so if the matter is not urgent, it would be better for customers to contact us either before or after next Thursday.”

Members of the National Union of Teachers (NUT) will join local government employees and other trade unions on a march through London culminating in a rally at Trafalgar Square.

The NUT has said the Government is failing to make progress on a dispute over pay, pensions and teachers’ workloads.

Havering Council has said that local authority run school will be required to have made arrangements by July 7. It is anticipated that these plans will not disturb ongoing examinations.

Trade union Unison has said carers, social workers, refuse collectors, street cleaners and teaching assistants will be among its members to walk out.

Linda Perks, regional secretary for Unison Greater London region said: “Council workers have kept on going in the face of four years of draconian Government cuts to keep local services in London running. They care for our elderly and our vulnerable, keep our streets clean and educate and look after our children. They deserve better treatment than they have had at the hands of this Government.”
