More industrial disputes are expected in the New Year at a well-known canning company after management and unions failed to resolve a row over pay. Members of the Unite union at the Heinz site in Wigan took strike action over the festive period. Heinz said it had “worked hard to improve what we already believed was a very fair offer” and was disappointed with the outcome of the talks. The company said the current offer to workers was equivalent to 4% one year and 3% in the next.
