I can appreciate this, I think to some degree (especially in a physical office) there is a degree of community required, and as long as there is a general acceptance that this kind of "other stuff" is either minimal or accepted in lieu of your "regular" work (as opposed to in addition to), I think it's OK.

My main concern, honestly, is not so much that the work is "beneath me" but more that I get pidgonholed doing that work. I know this isn't realistic, but I don't want come review time for people to say "it's great you do this stuff around the office/for the team/for the org" but it doesn't affect your metrics.

In some cases, I think the fear is being asked to do these things in a non-documented way means you have no evidence that you had these "extra-curricular" things you had to complete.

I'm fortunate I haven't had that happen to me, but it's a fear I always have at the back of my head whenever these sort of requests happen.
