Input:  Person1:       So , Lauren , I just wanted to talk to you quickly about our new customer support representative , Jason Huntley .  
 Person2:Sure , what ’ s up ?  
 Person1:        Basically , I ’ Ve got a few concerns about him , and the bottom line is , I don ’ t think he ’ s a good fit for our company .  
 Person2:Okay ... what makes you say that ? I thought you were pleased with his overall performance . Didn ’ t you just tell me last week how impressed you were with his attitude ?  
 Person1:        Yeah , his attitude is great , but he ’ s really unreliable . Sometimes he ’ s really productive , but then other times ... take last Tuesday for instance , he was forty-five minutes late for our morning meeting !  
 Person2:Well , I ’ m sure he had a perfectly good reason ...  
 Person1:        But that ’ s not the only thing ... you know , he really doesn ’ t have the best work ethic , I ’ m constantly catching him on MSN and Facebook when he should be talking to clients .  
 Person2:Yeah , but come on , Geoff , as if you don ’ t check Facebook at work . Look , you hired this guy , we ’ Ve invested a lot of time and money in his training , so now it ’ s up to you to coach him . Make it work , Geoff !
