The union Unite has announced a demonstration is set to take place at the Brewdog bar in Aberdeen on 25 February.

Called in response to the treatment of workers during the potential sale process at Brewdog, Unite said that staff have been left in the dark by the brand, as information spreads via the press rather than through direct correspondence.

This, according to Unite, is the latest in a long string of workplace problems for staff, including the abandonment of the real living wage, bar closures and the slashing of contracted hours.

This happens at the same time as founder James Watt allegedly tries to take back control of the brewer by investing £10m of his own money in a rescue bid.

On the possible sale of Brewdog, Unite general secretary, Sharon Graham said: “This sale is the result of years of catastrophic mismanagement – prioritising private equity returns over workers and a sustainable business.

“You cannot talk about restructuring without recognising the real people whose rent, food bills and childcare depend on these jobs.”

Meanwhile, Bryan Simpson, national lead at Unite hospitality, added: “This is the collapse of a brand once sold to customers as anti-establishment, now being auctioned to the highest bidder while workers and small investors are left to pick up the pieces.

“Workers have already paid the price with the abandonment of the real living wage, widespread bar closures, and now slashed hours.

“We demand clarity on job security and what protections will be put in place for workers and we will use every industrial and legal lever available to defend our members and secure what they are owed.”
