Geest is rumoured to axing 150 jobs as part of a streamlining operation.
The fresh produce giant is thought to be restructuring its business following its takeover by Icelandic prepared food specialists Bakkavor in May this year.
The company recently paid £44 million for prepared veg and salad producer Hitchin Foods.
The Wigan-based business, which employs 750 people, was snapped up as part of Bakkavor’s plans to strengthen its position in the prepared market.
No-one was available for comment at Geest.
