Over a quarter of the UK's workforce are denied access to the internet by their employers, it has been claimed.
According to research by T-mobile and YouGov, which studied 2,000 UK adults, almost half of employees surveyed have resorted to accessing the internet on their mobile phones.
The survey also found that 23 per cent of employees are subject to company policies banning them from accessing social networking websites, with seven per cent restricted from using Google.
Commenting on the findings, spokesperson Jenni Trent Hughes said cutting off the internet could be stopping employees from "using the tools that could help them work more effectively".
Search engines, newswires to key industry blogs and even social networking sites are "becoming increasingly important tools for young professionals", she added.
Research by Milkround Online last week found that 78 per cent of students and graduates are keen to work for internet companies, which is "no surprise", a spokesperson said, given the "huge growth of social networking websites such as Facebook and MySpace".
