Okay, so MY JOB is GREAT. There's no doubt about it. But the specific position I was hired for is not the one that sorts the letters (actually right now there are I think 3 people doing that job), and the only thing better about that position than mine is that in that job you're authorized to make up categories. Furthermore, if the new category is an area in which you have expertise, you're allowed take the job of answering those letters once there are enough of them. (This does not happen very often, but when it does it's usually a major victory for the department and for the individual involved.)
My coworker just anointed himself the "Ham Specialist". I'm not even sure I want to know what that means.... Well, either that or getting inappropriate in a letter to Santa on the subject of ham is just way beyond my scope.
