WORKERS at Anglian Water are to stage a 24-hour strike and a work to rule in a dispute over pay.

The GMB union said its members at the water company will walk out on June 12 and will work to rule and withdraw goodwill after warning that staff could lose up to �2,500 a year in pay because of changes to shifts.

The workers maintain sewage facilities across the region. Industrial action could impact on the supply of clean water, the clearing of sewage and on the safe discharge of sewage into rivers, said the GMB.

Anglian Water said there would be no disruption to services in the event of strike action going ahead, adding that only 235 workers out of its 4,000 employees were involved in the dispute.
