Smartphones and laptops are not only driving people to work longer hours but also encouraging them to take their job on holiday.
One third of people surveyed by BT said they were planning to check their work emails and voicemails while on vacation. These workers say they check in while on holiday because they feel a responsibility to do so and worry about missing important information.
Men find it more difficult to switch off from work, with 37 per cent checking office emails compared with 28 per cent of women.
This inability to leave the job behind creates friction with family members, the survey found, with one quarter of those who check work communication admitting to doing so surreptitiously to avoid causing tension.
Psychologist Corinne Sweet said: "If you can't stop yourself logging on or texting and it's affecting your personal relationships, then you need to think twice. Holidays should give you a chance to turn off and become aware of your behaviour.

"Try to spend a day offline and more time just hanging out with family and friends, or simply being alone. Holidays should be about recharging your own batteries, not just those of your laptop or smartphone."
Two in five, 41 per cent, of Brits also admit to logging onto social networking sites when holidaying with friends and family.
