OK, so we all agree that e-mail is an essential for any business, yes? Well, up to a point - but have you thought about what your employees actually use it for?
Cryoserver has done a lot of thinking about that, as the page I've linked to will confirm. 98 per cent of employees use it to discuss or organise their social lives. 90 per cent use it to send jokes around the firm, and 76 per cent use it to conduct non-work related business.
No, I wasn't surprised either. But it does say a lot about what an employer is actually funding for his or her employees - all of this costs money, and as Cryoserver points out, there can be data protection implications as well.
