The VP of Sales, Allison, has sent you an email relating to a recent IT problem and would like your response:

I have just been informed through my network that the Salesperson who quit last week is now working at our competitor. Apparently, he is bragging about how he has our entire company's customer list (not just his customers) with him and he is confident that he can poach from the list.I need to know how this was possible and what we are doing about preventing this from happening in the future if any other sales people decide to leave and do the same.Your attention to this matter is appreciated.
