Somerset CC staff members have rejected plans to reduce redundancy terms and payment protection.
Unison has informed managers that a ballot of members has turned down the proposals to reduce workforce costs by reducing protection for outgoing employees.
The council, which has announced that it intends to lose about 1,500 posts, had suggested a number of changes including the reduction of redundancy terms to the statutory minimum.
Unison regional organiser Helen Eccles said: “UNISON members have given us a very clear mandate with almost a 100% rejection of the employers’ offer, with this mandate we urged Somerset CC today to return to the negotiating table, work in partnership and negotiate a way forward to avoid potential industrial action.”
Unison branch secretary Nigel Behan warned that Somerset’s attitude to staff was putting services at risk: “If Somerset CC is to have the worst employment terms amongst south-west councils, then how in future will we recruit and retain the motivated and committed staff to deliver good quality services that our community here in Somerset deserve?”
