A new survey has found that people are working longer hours - with one in six employees now working more than 60 hours a week.

The DTI study, conducted by Management Today magazine, has sparked fresh concern about the work/life balance in the UK.

According to the poll of 500 workers, the number of women working more than 60 hours each week has doubled since 2000.

Trade secretary Patricia Hewitt said employers should be aware that long hours can lead to high stress levels - which in turn can hit productivity.

"Stressed workers with frayed nerves cannot perform to their maximum and employers know the damage this can do to commercial success," said the minister.

The survey also found that 75 per cent of employees work overtime, but only a third receive extra pay or time off in lieu.

It revealed that twice as many people wanted shorter hours than those wanting to win the Lotto.

Hewitt said that the government would take action to curb the long hours culture.

"More British workers are recognising that balancing quality of life and family is as important as a fulfilling career. People clearly want greater control and choice over working hours," she said.
