Sainsbury’s Haydock distribution centre was hit by industrial action again last night and workers have not ruled out a fourth strike.

The news follows one-day strikes on December 29, January 7 and January 13 after talks between the company and the Usdaw union broke down over pay.

Workers rejected a pay offer of £7.55 an hour before Christmas claiming they had been promised £8 to put them in the upper pay quartile for north-west warehouse workers.

Sainsbury insisted the dispute had not caused major disruption to its supply chain, however.
