Hundreds of workers at a Coca-Cola distribution centre in West Yorkshire are to be balloted on strikes in a row over pay.
More than 500 workers at the site in Wakefield are angry at a pay offer worth 2.5 percent, the Unite union said.
The union warned that if its members took industrial action it could have a “devastating effect” on supplies to supermarkets and pubs across Britain.
Regional officer Kelvin Mawer said he was seeking talks with the firm.
Mawer said, “Coca-Cola Enterprises (CCE) now face the prospect of a strike which we believe will have a significant impact on supplies of Coca-Cola during the hottest months of the year.
“Wakefield is one of the most productive and cost-effective sites in the UK. Yet CCE are effectively proposing a pay cut in real terms.
“How can a business like CCE expect its employees to accept a pay offer far below the rate of inflation when the same employees have contributed to the success of the business?”
