Stores across the UK could be affected after thousands of Asda workers voted against a pay offer with many prepared to strike.
A majority of the 8,000 GMB union members within Asda's distribution network, have recently voted to reject pay rises between 5 per cent and 7.5 per cent.
Nearly 70 per cent of the warehouse staff, lorry drivers and clerical staff in GMB rejected the rise. There are around 12,000 workers in total in the entirety of Asda's distribution network.
