Weetabix workers have gone on strike in a dispute over pay for unsocial hours after rejecting a new offer.

Members of the Union of Shop, Distributive and Allied Workers (Usdaw) at the plant in Burton Latimer, Northamptonshire walked out on Monday.

Usdaw area organiser Ed Leach said further strikes would follow the 24-hour stoppage unless the company changed its position.

Weetabix said it was "disappointed" by the strike.

Workers at the cereal bar factory eventually rejected a Weetabix offer intended to resolve the dispute and walked out at 19:00 BST on Monday.

Mr Leach said: "During the last fortnight we have called off strike action twice to allow for further talks and for the company to make an offer.

"The offer was put to a ballot. The majority of our members rejected the company's offer.

"We are disappointed that the company has indicated at this stage there will be no change to their position. If this is the case, then further stoppages will follow."

A spokesperson for Weetabix said: "We are naturally disappointed to see our cereal bars team on strike, but respect their right to do so."
