In general I agree with this sentiment, but let's be honest and remember that a lot of jobs are of the type "you are responsible for X, regardless of what time of day it is". In a reasonable place, that of course comes with the benefit that you can take time off whenever you want as long as X is handled, but I actually prefer the freedom/responsibility trade off of needing to handle shit in the weekends when required, but also being able to not come in to work when I know stuff is running as it should.
