Ford Bridgend: 'South Wales will be a ghost town'
Ford's engine plant in Bridgend is set to close in autumn 2020, with the loss of 1,700 jobs.
Union officials were told of the plans at a meeting with Ford bosses which include the offer of redeployment.
Workers were sent home after receiving a letter which said they will lose their jobs in phases from 25 September next year.
Ford blamed "changing customer demand and cost" for the closure plans and denied Brexit was a factor.
Workers spoke of the suddenness of the decision, while traders in the town said it would have an impact.
