Teaching assistants in Durham will take strike action on 8 and 9 November in the long-running dispute over changes to their contracts, their union UNISON has announced.
This follows a ballot over Durham County Council plans to move teaching assistants to term-time pay. Campaigners say this could see school support staff lose up to 23% of their wages.
93% of UNISON members who responded to a ballot voted for strike action.
The union represents around 1,750 of the 2,600 teaching assistants in County Durham. The smaller ATL union is joining the strike.
GMB union members will not be part of the industrial action, after members accepted a revised offer from the council, including two years' compensation.
Durham County Council says it has to pay TAs for term-time only, to avoid equal pay legal claims from other staff.
