Struggling French sliced ham and charcuterie firm Madrange has reached an impasse with unions over the firm's survival plan.

The company, which was previously considering a fire-sale, has argued that it must cut costs to regain profitability. Management wants to cut as many as 300 jobs, nearly a third of the work force.

Staff representatives are refusing to even express an opinion on the management's survival plan. Once a strong branded manufacturer, in recent years private label work has come to dominate the business.

The family-owned firm currently operates four manufacturing sites across France, including its Limoges head office, where no fewer than 135 jobs are on the line.
