Six out of ten Brits cannot switch off from their job even when they are at home.
This is according to a new survey conducted by health cash plan provider Medicash. The firm questioned 1,000 people across the UK and found that 60 per cent take the burden of heavy workloads home with them.
Those living in Birmingham were found to have the worst work-life balance (43 per cent of those surveyed). This is closely followed by London (39 per cent) and Liverpool and Manchester, where 36 per cent of respondents are unhappy with their work-life balance.
Glaswegians had the best balance at 83 per cent and this was followed by people from Norwich at 75 per cent.
Overall, those working in the arts and culture industry were found to have a good work-life balance (69 per cent).
Cary Cooper, professor of organisational psychology and health at Lancaster University, said that companies must do more to promote flexible working.
"Work smarter, not longer should be our mantra. Increasingly, we are seeing employees turning up to work ill and delivering little added value; presenteeism does not enhance but undermines productivity," he stated.
Sue Weir, chief executive officer at Medicash, added that the study's results are "very troubling" and can have health implications for staff.
"Keeping a good work-life balance helps both workers and businesses," she said.
Indeed, offering flexibility has numerous benefits for employers. Not only does it improve staff morale and retention, it can save a firm money.
Thanks to modern technologies such as conferencing calling systems and cloud computing, it is possible for many employees to do their work from home.
For a business this means that the amount of cash spent on things such as hardware maintenance, desk space and even electricity can be reduced.
Last week, Peter Boucher, enterprise commercial marketing director for Vodafone UK told the Guardian that his firm is looking at potential savings of £34 billion thanks to flexible working.
