A startling two-fifths of employees try to fit in up to three hours' work each day while they are on holiday.
According to a poll by workspace provider Regus, which surveyed 2,500 UK workers, 39 per cent do not relax while on their summer holiday as there is important work to be done.
Reported by hrmagazine.co.uk, around eight per cent will work over three hours a day on holiday, while 25 per cent claim they will be working on a reduced 'business as usual' mindset.
However, this could prove to be a hindrance in the journey towards an equal work-life balance - something a CEO needs to tackle head on.
Katherine Rake, chief executive of the Family and Parenting Institute, believes those on holiday should be 'switching off' work mode and enjoying their vacation instead.
She stated on cambridge-news.co.uk: "Employers need to support staff to truly switch off while they are on leave. Bosses must introduce company policies banning themselves and other staff from contacting those taking time off.
"If they can pledge to save the summer holiday in this way, they will be rewarded with more productive workers returning to the office. They will also be helping to defend family life," she added.
