I thought I'd pose this question as Arrsers may have experienced this. I have two colleagues who are at was with each other and are dragging in people around them, like a black hole of petty squabbling. Pretty simple really, can someone send a Cease and Desist letter to a part who has been sending slanderous email communications to a third party? If so, what are the legal (if any) implications of ignoring the letter. It is worth noting that despite countless requests to stop being a pair of little bitchy girls, these two continue to do flail their arms at each other.
