BRITISH workers are at increasing risk of burnout as the number of people working over 48 hours rises past 15 per cent, trade unionists warn today.

According to new TUC research, there are now over 3,400,000 employees doing excessive hours — up by more than 450,000 since 2010.

The number of people overworking had been in decline for more than a decade until the year the Tories came to power.
