Workers are drowning in a sea of email.
Global business communication specialists Pitney Bowes says office staff typically receive up to 200 emails a day.
US workers received the most, averaging 195 a day, followed by British workers receiving an average of 190.
The email overload is claimed to be giving office workers a new source of stress.
Now, major companies are sending staff on courses showing them how to communicate effectively while limiting their email traffic.
But some pychologists says clear policies can be sufficient.
By all means email colleagues overseas, says one, but if they are in the same room, just talk to them.
