Nope. I teach HS in another district and leave way before they do (except for the one in Jr. High, we leave about the same time now). I jimmied some classes around for the first day of K for DD#1 and DS, although with my schedule I wasn't able to do that for DD#2. Grandma filled in just fine that year, and since DH gets them off to school each day it's not like no parent is with them.
Occasionally I get things like "why don't you come eat lunch with me at school like so and so's mother?" My answer (besides "she doesn't have a job") is that since I teach I can't, but remember I take a personal day every year for Halloween, have been known to call in sick or take half a sick day for special events, and have every vacation and summer with them.
