Here’s a thought:

If a certain colleague spent even just half as much time visiting other people throughout the day, going from one cubicle to the next, chatting about godknowswhat, maybe… just maybe… that colleague could, oh I don’t know… do his or her own job instead of trying to pawn it off on our newest employee?

As a bonus, it would also virtually ELIMINATE any “despair” over how swamped said colleague is. The solution to staying caught up is to actually DO YOUR WORK!
