Having been in companies where my approach has been called everything from "lazy" to outright "damaging," this feedback was both rewarding and validating.
Edit: For those who are in jobs where you're putting in those long hours, I can tell you there are managers out there who believe in the message here. I have three of them working for me right now and I constantly reinforce the philosophy of working sustainably. Don't settle for less than a manager who respects you the person--not just you the engineer!
