Peter’s Food Service, a UK manufacturer of pies and pasties, is reviewing operations at its plant in Bedwas, Wales, in a move that could potentially cost 90 jobs.

Trade union Usdaw said it has entered talks with management over the potential redundancies at the site near the town of Caerphilly.

Jason Stevens, Usdaw’s area organiser, said: “We’ve been informed by the company that they have reviewed the business and propose reducing production at the Bedwas site. Clearly this is very bad news for the staff affected.”

The company, founded in the 1950s, supplies fast-food outlets, supermarkets, sports stadiums, fish bars, restaurants, cafes, sandwich shops, independent retailers, schools, hospitals and hotels throughout the country. It makes 3m pasties a week.

Usdaw said in a statement that it is “interrogating the business case for the proposals”.

“We are seeking to minimise compulsory redundancies and ensuring the business has a viable future. In the meantime, Usdaw is providing our members with the support, advice and representation they require at this difficult time,” it said.
