Doing undergraduate teaching, having really large classes, having to manage a number of TAs, doing counselling of undergraduate students about where they want to go and that type of academic mentorship, that is what we call academic housework. That is disproportionately placed on women faculty and junior faculty. Those are places that male faculty have often been mentored and encouraged to avoid like the plague. You see a disproportionate care work within academic environments, specifically on teaching.
Yes, we should be places that do research and generate knowledge, but we should also bring students and get them involved in that. That takes time and energy, because students come and they're energetic, but they don't know about a certain thing, and you have to ramp them up. Once you ramp them up, they go off to someplace else. That affects productivity.
Teaching, supervision, all those types of things.... Sometimes you can get an incredible student who is with you long enough and he or she can improve your productivity, but if you have many students and they're typically at an undergraduate level, that is a lot more work in terms of sustainment.
I hope I answered your question.
