Heinz may be forced to enter strike negotiations
Unite have warned further industrial action could be staged by Heinz employees next week.
Strike negotiations may be required by Heinz bosses after leaders of a union representing their workers warned more industrial action could be taken over Christmas.
National officer for food and drink at Unite Jennie Formby said that her organisation is open to talks but the company needs to make an improved offer before a resolution can be reached, the MEN reports.
Industrial action was taken after employees at the Wigan plant rejected a pay offer, which resulted in a 24-hour walkout being staged this week.
And further picket lines could be created if strike negotiations fail to resolve the issue, with Unite saying another round of action could be taken over the coming days.
Following this latest walkout, the trade union stated that two million fewer cans of Heinz products were produced as a result.
This comes after London Underground accused Aslef of refusing to enter talks in order to prevent tube staff staging strikes on Boxing Day in a row over pay.
