And that right there sums up the patriarchy :/

It wasn't an issue when I wasn't working (naturally because I was home all the time anyway) but now we are both working it's usually DH that takes the day off if need be because his work is more flexible like that than mine so we work it out as it happens. As a teacher they need to arrange a casual to come in and cover me, but with DH, there are more than enough men on crew to cover his work. I do work at the school where our youngest 3 go so if they got sick when I was working I know they would be right in sick bay or if they were really bad I have someone I can call to get them. Dh works out of town so if it was a sudden thing it would be harder for him to arrange it, but if we knew a kid was sick it is easier. He also works a 4on-4off roster so he technically only works 6 months of the year anyway.
