The world's biggest soft drinks bottling factory is set to be hit by two 48-hour strikes.
Nearly 400 workers at Coca-Cola Enterprise's Wakefield plant, which produces 6,000 cans and 1,650 bottles of soft drinks every minute, will strike on 26 and 27 July and 13 and 14 August after negotiations over pay failed. Workers at CCE's Milton Keynes plant will also strike on 27 July.
Stephen Moorhouse, CCE's vice president of UK operations, attempted to ease fears of potential supply problems, claiming there were sufficient contingency stocks to maintain supply.
However, Unite, the union organising the strike, said workers would also begin an overtime ban from 23 July, which could leave CCE struggling to cope with demand during the summer. "CCE will lose 1,000 working hours as a result of the overtime ban," said Unite regional officer Kelvin Mawer. "Shops now face the prospect of shortages of Coca-Cola."
