Workers at a Greencore cake production site will stage a 24-hour strike next week in protest at changes to terms and conditions.

According to Unite, the union representing workers at the facility in Hull, the company has imposed cuts to pay of up to GBP40 per week.

Last year, an employment tribunal forced Greencore to pay compensation to workers totalling GBP1.2m. In 2001, employees had agreed to temporarily forego premium pay rates to "help the company during difficult trading". However, when trading conditions picked up the company did not revert back to original terms of employments.

According to Unite, the latest cuts are an attempt by Greencore to side-step the tribunal ruling by issuing new contracts.

"When brought into line by the law, Greencore simply ignores it. Imagine if this workforce had a similar disregard for the laws of this land? They would face jail, not the praise of analysts revelling in the GBP70m in profits alone this company generated last year," union officer Jennie Formby said.

Greencore was not available for comment at the time of press.

It is estimated that approximately 500 workers will strike next Wednesday. The Hull facility manufactures various products, including speciality cakes for Asda, Tesco and Sainsbury's.
