Actually, as an afterthought, people might be interested in this.....
Back in October of last year, a tech in Swansea took a call from someone who wanted pictures removed from her webspace and didn't know how to do it. The tech helpfully showed her how it was done but she wasn't all that clear on the way it was done so he offered to do it for her. She gave him her webspace address only to find the pictures were of her in extremely pornographic photos. The tech promised to remove them for her.....but only after he'd emailed the link to a load of people in Matrix Court including some team leaders and above, some of whom passed them on to others etc....until one person objected and reported it, as they weren't happy about having a link to such material in their work Inbox.
An internal investigation was launched and the original tech in question was expecting to be severely booted and/or sacked for using the company email system for sending out this sort of filth.
It became apparent that if he was to be disciplined for sending it, then so were the others who passed it on as well, but seeing as some of them were team leaders and/or above, the whole incident was whitewashed apart from an email which went around to everyone in matrix Court warning them then any improper use of the email system would be dealt with.
So you can get away with 'breaking the rules' at NTL and be guilty of sackable offences, as long as you are high enough up the corperate ladder
