GMB, the union for Asos workers, is to step up campaigning activity outside the company's Barnsley warehouse today (5 October) after the conclusion of a long-running complaint found in its favour.

The Asos facility in the north of the UK, which is run and managed by logistics firm XPO has been the site of a long-running GMB campaign to "win respect for the fast-fashion retailers' workers".

GMB says the dispute stems from a decision by XPO, which runs the facility, to sign a deal with fellow union Community regarding union representation – a move which is understood to have gone against the workers' existing arrangement with GMB.

The TUC Disputes Committee ordered Community to pay a fine of GBP24,532 (US$31,974) direct to GMB after the ruling and ordered it to formally seek recognition for GMB at the Barnsley XPO Logistics site.

"GMB is the true voice for Asos workers and be assured we'll be stepping up our battle to win dignity and respect here in Barnsley," says Neil Derrick, GMB regional secretary. "We're firmly on the side of Asos workers and we'll continue to be a voice for them. These are our people, not machines and we will ensure they are treated properly.

"Workers at Asos have been crying out for union representation of their choice, not of their bosses' - and that's what they're getting with GMB every day," Derrick adds. "Until Asos bosses live up to their claims of fashion with integrity at Grimethorpe, our campaign to win respect for Asos workers will continue."
