A staggering new analysis from the Trade Union Congress (TUC) has exposed the scale of exploitation silently plaguing the UK’s workplaces: last year, workers were effectively forced to hand over £28.5 billion of their own wages back to their employers.

While corporations enjoyed the fruits of this free labour, one in eight UK employees — a staggering 3.5 million people — were pressured into working extra hours for absolutely nothing in return. According to the TUC’s findings, the average worker sacrificed £8,100 of their hard-earned pay in 2025 by clocking up an average of nearly seven unpaid hours every single week. In total, the workforce contributed a mind-boggling 1.2 billion hours of labour for which they were not compensated.
