I've got a full service line up this semester, as usual.
Personnel (which everyone with tenure is on in my dept)
College Committee (chair)
University Committee (not a hard one)
MA Thesis advisor (there's no other way to count this)
And still, the requests and demands for service come. At this point, it's mostly not committees, per se, but ad hoc stuff, or short term stuff, or just do this four or five hour task stuff; you get the idea.
Yesterday, I got a few requests (some were blanket requests to groups of people, some were individual):
Judge students' work thing
Come to a meeting to be a warm body
Be on one of two ad hoc committees
Another judge students' work thing (but very different)
Each of these things is important to the person who's asking for more service. I know that.
I also know that there are people in my department (and elsewhere) who sit on a committee, do none of the work, and then complain about being on the committee loudly and often, and who don't get additional requests (because their committee work is crap when they do it). And there are people in my department who basically teach the same courses over and over (it's not that they're lazy, necessarily, but that they have a creative writing workshop or intro to this or that subfield, and they do it in whatever way they've always done it, and that's probably fine).
And the same is true across the university; and in a lot of subjects, they basically teach the same basic classes without huge change, semester after semester. (Maybe that's my imagining? Maybe intro algebra changes radically? Or intro chem? But maybe they think the same about a Shakespeare class. You only have 34-36 plays to choose from, right? Add a few sonnets, and maybe RoL and easy peasy.)
Right now, I'm resentful of every single request for additional service stuff.
I need to go to the mall and measure my blood pressure.
