Staff at Princes Food in Long Sutton have begun strike action this week in a row over pay.
Unite say previous pay offers of between four and seven per cent have been revoked after the company was sold to a new firm Newlat SPA.
Strikes began in Cardiff last week after a three per cent pay rise was offered.
Other sites are also taking place at other sites from this week.
Long Sutton first went on strike on Tuesday (January 7), before further strikes today (Thursday) and on January 14 and 16.
“Freezing temperatures won’t stop our members,” a spokesman for Unite said. “Spirits were high on strike day one at Princes, Long Sutton.
“Members were joined by our regional secretary Paresh Patel and representatives from the local trades council.”
Unite general secretary Sharon Graham said: “Newlat need to get back round the negotiating table before its customers discover they won’t have any products on their shelves.
“Our members work in back-breaking roles on low pay and want a fair slice of the pie.
“Newlat make 20 per cent of all their revenues in the UK and are making money off the backs of these workers. Yet they want to shortchange our members. Unite won’t stand for such behaviour and back our members 100 per cent.”
Unite national officer for food, drink and agriculture, Paul Travers, said: “Newlat borrowed huge sums of money to buy Princes and is now looking to cut corners and penny pinch to pay that money back.
“Unite won’t let them do so with our members’ livelihoods.
“Newlat can avoid this strike, which is one of their own making, by coming back to the negotiating table with a new and improved pay deal for our members.”
Princes released a statement on Monday stating that staff had above inflation pay rises in previous years ad said contingency plans had been put in place.
Angelo Mastrolia, chairman of the board of directors of Princes, stated: “It has become increasingly clear that resolving this dispute with Unite is becoming more difficult.
“We have engaged in discussions with the Union for several months, proposing an above-inflation pay rise and offering to backdate this to April 2024 during the negotiations.
“However, Unite has informed us that they would not permit the company to proceed in this manner.”
