Workers at the Tangerine Confectionery factory in York will begin fresh industrial action in the run-up to Christmas.
Members of the GMB union voted to reject a 1% pay offer that led to a four-day strike action back in November.
Tangerine increased its offer by 0.25%, with a 15-minute break, and the workers have until Friday to respond or the deal will be taken off the table altogether.
“I am disappointed with the absence of any proper dialogue from Tangerine,” said Ben Kirkham, GMB organiser.
“GMB members have maintained their dignity whilst facing continued provocation to their job security. This clearly undermines the relationship Tangerine has with its workers and shows the dispute is justified. The cost of living in York is at its highest in the region, however workers at Tangerine are paid on average £4,000 less a year now than 10 years ago.”
A spokesperson for Tangerine Confectionery stood by what it said to British Baker in November that it was “surprising that some York employees have taken this step, particularly when [the company is] investing more than £8m at the site during a period of intense competition within the UK confectionery market”.
Tangerine is the UK’s largest sugar confectionery and branded popcorn manufacturer, and its brands include Butterkist Toffee Popcorn and Princess Marshmallows.
