Workers in the UK are overwhelmed by e-mail and spend the equivalent of 36 office days a year writing them, according to research.

A study by O2 Business – which has launched its own hassle-free conference calling app O2 Just Call Me – revealed the average UK worker spends 288 hours writing e-mails every year, sending 4,118.

We also receive 6,225 and more than a third of employees feel overwhelmed by their inboxes.

While 59 per cent of us use e-mail more than any other form of communication, more than half (56 per cent) believe a call is more effective.

Here in London, we receive the second-most e-mails a day, around 39 on average, compared to a meagre 17 a day for the Scots but much less than the 48 in the south west.
