our fat ugly grassing facilities lady sent an e-mail out a few years ago detailing upcoming 'company events'. I have a habit of forwarding peoples e-mails to my mate after editing the words somewhat for a bit of a chuckle. anyway, reading the emails, hit forward, editied it (quite brutally, calling her a fat waste of space, hairy armed cunt, useless time consuming bitch.....) then forwarded it back to her. walked away from my desk, got half way down the office floor when i realised, tried re-call - too fucking late. went straight to my boss who (thankfully howled with laughter) told me he would sort it. 2 days later sat in-front of hr , loss of bonus (£745 quid), final written warning and told that she wants to get me fired and is trying to take it further.
needless to say, I still edit e-mails, i'm just a bit more careful.
