ASDA has been accused of trying to stymie support for GMB union after depot managers were given the go-ahead to ballot for union recognition.

The Central Arbitration Committee granted the ballot for more than 1,000 managers working at the supermarket’s 23 depots after GMB provided a petition showing more than 60 per cent of workers backed the move.

Today, GMB national officer Nadine Houghton said: “If the vote is for recognition, GMB will negotiate directly with company bosses over pay, terms and conditions — things which have been significantly eroded since Asda was brought out and asset-stripped by private equity owners TDR Capital.

“Since being granted the vote, Asda has attempted to stymie support for the union by offering a pay rise and other concessions.

“But workers know this was only achieved because they started to organise into the GMB.  

“Union recognition is about winning improvements now and for years to come while protecting what is achieved.”

Asda was contacted for comment.
