Allowing employees to work remotely actually increases productivity, according to the results of a survey from software company Sirenic.
Around 70 per cent of the 300 London business people surveyed claimed that they would be more effective if they could work flexibly, although only 49 per cent said that their companies offered that option.
The most popular reason for needing to work away from the office was attending business trips and meetings (46 per cent), while six per cent needed to work from home to accommodate holiday changes in childcare arrangements.
Employees are unlikely to exploit flexible working, the company claimed, as 81 per cent of people whose firms offered the option had worked remotely for less than three days in the past month.
Chairman of Sirenic, Bertrand Lipworth, said: "Some employers are still wary of offering flexible working, as they believe that employees will take advantage.
"But remote working is about trusting people to use their time more efficiently - catching up with emails while on the train, between meetings, commuting (by car even with voice access), working from home while waiting for deliveries or checking emails whilst on a business trip."
