And finally…average worker spends an extra unpaid day at work each week

Those in the IT and Telecoms industry do the most additional hours each day (3.73), culminating in an additional 9 hours of work per week.

Interestingly, just under half (47 per cent) say it’s because they feel they don’t have enough time at work to do what they need to. Half (50 per cent) of all UK workers say they feel it’s an obligation to work beyond their contracted hours.

The findings, published by UIA Mutual Insurance, further show that over a third (35 per cent) of workers have no idea what the legal limit of hours worked per week should be, 13 per cent do not know the hours they are contractually obliged to work, or their employer is supposed to offer them.

Tim Roache General Secretary of GMB Union, said: “It’s a scandal that overworked Brits are putting in around eight hours unpaid overtime every week. That adds up to dozens of days a year where people don’t get to see their families, friends and loved ones. It’s no wonder wages in the UK are stagnating when people feel under pressure to put in so much unpaid work.
