Around 80 engineers at Weetabix’s Kettering and Corby factories will take part in strikes this summer, in protest at the company’s ‘fire and rehire’ plans.

The union Unite has announced that their members are due to participate in a series of one-day strikes during June, July and August that are yet to be scheduled. The strike action is being taken over Weetabix’s decision to issue the engineers with new contracts and work patterns, which Unite says will result in major cuts to shift allowances, costing some engineers up to £5,000 per year.

In a statement to the BBC, Weetabix responded: “We are naturally disappointed by the result of the reported ballot from union Unite, but respect the voice of our workforce and their representatives.

“Our success over nearly 90 years is built on a strong relationship with our workforce. We will remain in close consultation with them and are confident that together we can avoid any product shortages, while we implement necessary new ways of working to keep us competitive for the next 90 years and beyond.”

Unite regional officer Sean Kettle said members were “incensed at the company’s unacceptable behaviour” and that shortages of Weetabix supplies this summer could be avoided “if Weetabix withdraws its fire and rehire threats and engages in constructive negotiations with Unite’s representatives.”
