Nestle is cutting almost 300 British jobs as it moves production of one of its chocolate biscuits to Poland.
The job losses will be from sites at York, Fawdon (near Newcastle) and Halifax in northern England and Girvan in Scotland.
Nestle said production of its Blue Riband bars will move to a factory in Poland.
The GMB union vowed to fight the cuts. General Secretary Tim Roache said: “To shift the production of an iconic British brand like Blue Riband to Poland is completely unacceptable.
“Nestle are throwing people’s lives, and those of their families, into turmoil for the sake of increasing profit margins.
“These factories should be exporting chocolate – not people’s jobs.”
