Around 400 workers will lose their jobs later this year after it was confirmed that the Walkers plant in Peterlee is to close.
Parent company PepsiCo announced its decision yesterday, just two months after the news first broke that production at the Stephenson Road site was likely to end.
Now, PepsiCo has confirmed it will close the facility by the end of December 2017.
Crisp production is expected to switch to elsewhere in the UK to ensure the company’s “long term sustainable growth”.
Tracey Foster, Peterlee manufacturing director at PepsiCo UK, said: “We would like to emphasise that this decision in no way reflects the performance of our colleagues at Peterlee and we remain very grateful for their hard work and commitment.
“Our priority now is supporting and providing assistance to our colleagues who are impacted by this decision as we move into the process of consulting with employees on an individual basis about what this means for them personally.
“Peterlee has been an important site for our business but the proposal presents significant productivity and efficiency savings crucial for ensuring the long-term sustainable growth of our business in the UK.”
