Nutella fans across the globe are scrambling to stock up as news spreads of a strike that threatens to cut a quarter of the world’s supply.

Workers at a factory in France’s Villers-Ecalles plant that produce the popular hazelnut and cocoa spread are embroiled in a pay dispute, calling for a 4.5 per cent pay rise along with a 900 euro (AUD 1450) bonus.

Production at the factory accounts for a whopping quarter of the spread’s production, pumping out 600,00 jars a day.

The strike began on March 27, and with 160 of the plant’s 350 workers refusing to accept the latest offer of a 0.4 per cent increase in pay looks likely to continue for some time.

Workers have stopped trucks from going in or out of the plant, though one of the factory’s four productions lines is apparently still in operation.

Pickings may be slim for many countries, but thankfully the strike won’t affect Australians given the nation’s supply is produced locally in New South Wales.

Crisis averted.
