Details all too vague I'm afraid. Unless I've missed it I can't establish exactly where the images were recorded/made.
If they were taken during working hours and in the confines of the Tower or within the buildings then I've little sympathy but until these facts are established I'll defer judgement.
it's not MSN, it's the Mail. The same story is in the Sun, though as it's virtually word for word, I can't say who plagiarised it from who.

Well I went with the first viable link given, by 1ozzy with MSN in the text of it so I surmised.....well, I’m sure you can guess!
Even if it was at work wouldn't an official warning have been enough rather than dismissal? Silly stupid thing to do but losing your job seems a bit harsh to me.
