This is something that's been winding me up lately, so I wanted to know what everyone thought.
I work in a university as a course admin. The office I currently work in only handles a small number of courses but they are mostly UG and very popular, so I run the most popular UG ones with two other colleagues - we take a year group each. I'll call my colleagues "Eric" and "Adam". Eric is very easy to work with - Adam is fine to have a joke with, but is becoming a pain in the rump.
Basically, while we have our own general duties, if something comes in that needs doing and the usual person isn't there, or if it's an easy fix, Eric or I will handle it ourselves. Adam will not. Many times I have come back from a meeting to find something important came up that Adam didn't touch because it's not his job. Just last week he was wrestling with a student's marks profile and found a mark in it that shouldn't have been there - he could very easily have removed it himself, but instead he looked up who had put the mark in (me), handed it to me and told me to do it. Since I was in the middle of something else he then had to wait half an hour asking constantly "Have you done it yet?" while I wanted to scream "For pity's sake, Adam! Do it yourself!"
I've been gritting my teeth and bearing it because, all being well, I intend to retrain from September so won't have to put up with him. However, I dare say there will be other times this comes up. Is there a polite, professional way to suggest he try focussing on helping the student rather than "not my monkey", or is this something best left alone?
