Among the mitigating strategies discussed included locking ones profile and site, using all security features possible to confirm information got only to those it was intended to reach, and putting out as little detail about oneself as possible.

London -The average worker spends two-and-a-half hours writing e-mails every day, researchers have discovered.

A poll found that more than a quarter of most employees’ time is wasted sending, receiving or sorting out e-mails instead of doing their jobs.

That means that every year workers spend some 81 working days hunched over their computers – often e-mailing other people in the office.

The research points towards the technology-driven culture that has taken over, where putting in the hours is what is important, regardless of how much work you actually do.

The poll was carried out in the US by the respected McKinsey Global Institute and was based on a typical working week of 46 hours.

Assuming an employee spends 13 hours a week on e-mails, that works out to 28 percent of the time they are at work.

By comparison, employees spent just 6.4 hours a week, or 14 percent of their time, “communicating and collaborating internally”.

According to McKinsey, making changes to how people use computers, such as using more social media, could make them up to 25 percent more productive.

The findings are the latest in a series of polls which call into question whether or not the computer revolution really is a good thing.

A recent survey found that the typical working day lasts from 7.17 am to 7.02 pm because employees are checking their work e-mails on their phones outside office hours.

In a separate poll, half of bosses have admitted that their most productive time is in the car on the way to work as they are not so distracted.

Relationships expert Jean Hannah Edelstein said that e-mail has its place but that it should be used carefully as it “cuts us off from people”.

She said: “It can cut off essential aspects of communication that can only be via face-to-face contact, like tone of voice, facial expressions and body language.

“Having the conversations in the first instance in person is the best way to get to the heart of any matter.

“If you’re e-mailing people who sit next to you, it may be time to think again.”

Edelstein added that some people also use e-mail to avoid a difficult conversation or a confrontation.

She said: “Turning to e-mail can even escalate a conflict, such as if you write a long e-mail rant about something that may be more easily clarified and sorted through a face-to-face conversation.” – Daily Mail
