Emails to be abolished for 80,000 staff

It is now the turn of emails to be retired as before them letters and faxes. Thierry Breton, the managing director of the huge information services company, Atios, has decided that within the next 18 months, emails between the company's 80,000 staff should be abolished abd substituted by internal 'chat'. The company discovered that too much time was being spent deleting the emails every day by the staff. In fact, on average 100 emails a day per person with 15% of thos emails being useless meant that every person spent between the company and home 15-20 hours a week to check and respond to emails.
Would you prefer to use 'chat' rather than emails for work? Would it save you time?
