Workers at an Asda superstore in Hampshire are set to start a historic 48-hour walkout later this week.

More than 100 GMB members working at the Gosport branch on Dock Road will be going on strike from midnight on Friday until 11.59pm on Saturday.

Workers had voted in favour of industrial action in December last year, but agreed to call off the strike to allow further talks and vote on a new management offer.

However, union members rejected the company’s offer and voted a second time for strike action.

Nicola Nixon, GMB Regional Organiser, said: “GMB members voted to stand up to their employer in December and they’ve done it again in January and February.

“Counter proposals have been made to the company to settle the dispute, but Asda has failed to come back with any improvements.

“We originally gave Asda until Tuesday as a show of goodwill, but no improved offer materialised and so our strike will now go ahead.

"Our members are determined to stand up to Asda and their management and say enough is enough.

“They should be able to come to work without threat of bullying or putting their health, safety and well-being at risk.”

An Asda spokesperson said: “We have met the GMB on several occasions recently, including mediation at Acas, to try and agree a fair solution for all colleagues in Gosport.

“The proposals we put forward include the appointment of an independent third-party organisation to establish the facts regarding GMB’s complaints and report back jointly to both parties.

“Unfortunately, this proposal was rejected by the GMB membership. As most Gosport colleagues are not members of the GMB and will continue to work as normal during this period, we are confident there will be minimal disruption to our operations.”
